[vim] Side effects of extending 'matchpairs' ?

When editing HTML files with Vim I pondered about extending the
'matchpairs' setting for editing convenience. The default is

matchpairs=(:),{:},[:]

For the HTML editing purpose I temporarily change that to

matchpairs=(:),{:},[:],<:>

I'd like to hear opinions about making that a fix change in the
configuration file. Or keep it an ad hoc change on demand? Could
there be any undesired side-effects I didn't think of when making
it persistent?

You can use vim's auto commands to make that happen for only HTML files
if you like.

autocmd BufNewFile,BufRead *.html set matchpairs=(:),{:},[:],<:>

Personally I stick a bunch of Unicode pairs in there, too.

I keep showmatch turned off, so I don't know if the worst case is worse,
but, daily drive over a year, no issues with manual % matching.

Yes, I thought about making it file-type specific.

Interesting. And funny that the page exactly asks what I was looking
for. (BTW, thanks for the Unicode text file you linked on the page.
Very useful.)

Good to know. Exactly the experience feedback I hoped for. Thanks.

I think I'll even try to make it persistent and see how it evolves.

I use this for C++ files, no undesired side-effects so far. It works.

This is great! - I didn't think of C++ (despite using it occasionally).

There's a buglet,
set matchpairs=(:),[:],{:},<,>
should be

set matchpairs=(:),[:],{:},<:>

BTW, for C++ it works also nicely on _nested_ template expressions
(like with the other three bracket types). And also Vim's brackets
operator expressions, like y3a( or d2i{ , extend the (, {, [
operations nicely on < as in c2a< .
