Why not use pure HTML / CSS / JavaScript? I see several advantages:
The web app will not depend on any framework which may be deprecated with
a new version and would require a complete rewrite, like it happened with
ExtJS.
Progressive enhancement
(https://en.wikipedia.org/wiki/Progressive_enhancement) should be used in
order to have the basic functionality (e.g view / add / remove torrent)
working without JavaScript if someone is using a browser addon that blocks
JavaScript like NoScript / uMatrix or a command-line browser like Lynx.
The idea of progressive enhancement is that JavaScript should not be a
required but it should be here to enhance the user experience (e.g using
AJAX or WebSocket for automatic refresh of torrent download / upload
information, add / remove torrent without page reload).
I think any JavaScript framework don't really supports progressive
enhancement and it also has the downside of adding a dependency that would
need a complete code rewrite in the future. Security vulnerabilities could
also be introduced by a JavaScript framework (it happened in the past).
Using pure HTML / CSS / JavaScript may take a bit more time to develop but
in the end it will be easier to contribute for most people since there is
no need of knowing a specific framework like ExtJS, AngularJS, Angular,
React, Vue.js, Ember.js (who knows which trend will come next and
deprecate all other frameworks...).

I've actually been getting frustrated at the lack of mobile support
myself. I've been using Vue.js a fair bit elsewhere, the ES6 requirement
isn't an issue, and ES6 makes JS far nicer to use.

I see plenty of disadvantages. There is a reason people don't reinvent the
wheel, as time is better spent elsewhere.

If someone is using a command-line browser I'm sure they can work out how
to use cURL to send requests to the API to add a torrent. I'm far from
convinced the added complexity of having the web-app degrade gracefully in
the event of no JS is worth it. You would end up duplicating a lot of
work.

Security vulnerabilities can be introduced by writing all the JS yourself,
I fail to see issue here.

I would argue that this actually makes the barrier of entry higher than
using a framework. Using a framework means there is a subset of people who
have an understanding of the pattern and application design. Writing it
all from scratch means there would be no one outside of Deluge familiar
with the design.

By the security vulnerabilities, I meant the Deluge developers have
control over it, they will not depend on security vulnerabilities of a
third-party framework.
Note that if Deluge chooses to use another framework, they may face the
same problem they had with ExtJS, the framework may get deprecated and
they will have to rewrite everything.
This is not the case with pure HTML / CSS / JavaScript, for example I made
an app several years ago and it is still working great without changes and
without using a deprecated framework. In some cases, a few functions need
to be replaced but that's all.
I recommend this video of the creator of PHP, mostly talking about backend
frameworks but the idea is the same, it may add unnecessary dependencies,
complexity and processing that can affect the performance also:
