I agree with you in that in many cases tags can be replaced by saved
searches. Last time I did it, i.e. used saved searches to distinguish
messages from different mailing lists, the result was that it took very
long time (something like 5 seconds) to show notmuch-hello screen. There
is a bug in notmuch hello, as I described in
id:"87wrtz3pw2.fsf@steelpick.2x.cz".

Additionally, I compared the speed of command line searches for tags and
for the whole email addresses and even without the bug mentioned above,
the search for to: is usually slower than the search for tag:.

And finally, there are some mailing lists, which changed their address
in the past or have multiple aliases and in this case you always has to
use a more complex search to match all messages to that mailing list and
these searches are even more slow than tag searches.
