> 1. If you customized it to speed up agendas, are agendas still slow on the latest main?

I disabled org-agenda-use-tag-inheritance but I can't provide a lot of feedback because I don't use many tag filters:

1. I disabled it in a batch script that exports my agenda, though it doesn't actually speed up the agenda (even with org-element-use-cache disabled); I guess it's because the agenda view I'm exporting doesn't do any filter (in particular, filter by tag).

2. I disabled it in my .emacs, but I guess it has no effect because I also disabled org-use-tag-inheritance, because I've never needed tag inheritance.
 
I temporarily enabled org-use-tag-inheritance and org-agenda-use-tag-inheritance and opened an agenda that filters by tag (it combines 4 one-tag filters), it seems to run almost as fast; 25 to 26 seconds with tag inheritance enabled, whereas with tag inheritance disabled it takes around 24 seconds. These are manual measurements which may be 1 or 2 seconds off, so you may want to measure it more precisely; they may take the same time. Anyway I don't see slowness due to tag inheritance in agenda.

Hello,

We have a customization `org-agenda-use-tag-inheritance' that controls
whether agenda searches should use tag inheritance or not.

One of the main motivations to introduce it was that agenda searches
could become really slow when resolving inherited tags. However,
inherited tags can now be retrieved very fast, after org-element-cache
has been enabled by default. At least, it is the theory.

I'd like to hear from the users who customized
`org-agenda-use-tag-inheritance':

1. If you customized it to speed up agendas, are agendas still slow on
   the latest main?

2. If you customized it for other reasons, may you please explain your
   use case?
