Thanks for offering this patch.

I think we've thus far deliberately avoided exposing property
manipulation from python because properties have (by convention i think)
tended to be things that are set or cleared only by the notmuch indexer
itself.  (see notmuch-properties(7) for description of those properties)

We do expose this functionality in the library, so it's not the end of
the world to expose it in the python bindings, but i do worry a little
bit about encouraging people to fiddle with markers set by the indexer.

as nomtuch-properties(7) says:

       Extensions  to  notmuch  which make use of properties are encouraged to
       report the specific properties used to the upstream notmuch project, as
       a way of avoiding collisions in the property namespace.

So: no objections from me to the idea of the functionality here -- if
someone thinks this is useful for some project, i hope they'll speak up
for how they plan to use it.

That said, i'd love it if at least the docstrings for functions which
modify properties included some concise, thoughtful suggestion that
encourages collaboration with the community and urges caution when
potentially tampering with properties used by other parts of the
ecosystem.
