I think it would be great if the querystring template tag also had a
feature to remove all queries that start with a specific prefix.
I believe adding a feature that removes all queries starting with a
specific prefix would be useful when excluding certain items from filtered
query parameters.
{{{
class ChangeList:
...
def get_query_string(self, new_params=None, remove=None):
if new_params is None:
new_params = {}
if remove is None:
remove = []
p = self.filter_params.copy()
for r in remove:
for k in list(p):
if k.startswith(r):
del p[k]
for k, v in new_params.items():
if v is None:
if k in p:
del p[k]
else:
p[k] = v
return "?%s" % urlencode(sorted(p.items()), doseq=True)
}}}
This feature is actually one of the functionalities provided by the
`get_query_string` method in the `ChangeList` class, which serves almost
the same purpose as querystring template tag.

Comment:

Hello Antoliny, thank you for taking the time to create the ticket!

I can see the use case in the admin, but to be honest, this feels somewhat
like an antipattern when considering the `querystring` template tag in
isolation. Before completing the triage, could you share how you envision
integrating this feature into the current syntax? I'll mark this as
`needsinfo` for now, but please reopen it once you can provide those
details.

Thank you again!
