In my usecase when I toggle a tag to a thread in notmuch-search, it is
applied to all mails, obviously, and if I want to do per-mail tagging I
go into notmuch-show. To answer your question I'll give an example:

Suppose I have just some subset of a thread's mails tagged "+inbox" and
I toggle pressing "i", then all the mails in that thread are marked
"+inbox" and if I toggle again all are "-inbox". So removing a tag for a
subset of the thread's mails is just a matter of toggling twice.

I can always go in notmuch-show and do per-email tagging using toggles,
say after I removed the "inbox" tag in the example above by toggling
twice, I open the thread in notmuch-show and press "i" to toggle the tag
back on any specific email.

I'm using this for some time and it works really well :)

Yes, I agree that it's better to provide mechanism than policy because
workflows are so different. Tag toggling is just another mechanism, it
can be customized, for example, when you toggle on a thread of which
some mails already are tagged, should it add or remove that tag? This
can be configured through a variable.
