I don't mind formalizing that reviews are done on phabricator only. 
However following projects that way would, most probably, have one 
quite notable drawback compared with the current mailing list based 
approach:

Right now, it's easy to distinguish between mails requiring different 
levels of attention; ones with me in the To or CC fields are more visible 
and I try to read all of them. I have personal Herald rules that CC me on 
topics that I track. But I also browse the rest of the mails (quickly 
glancing usually only) for other topics I might be interested in.

My suspicion is that if the mail delivery is in the form of a personal 
subscription directly from Phabricator, it becomes much harder to 
distinguish mails that stem from just following a project as a whole, vs 
ones where I'm specifically CCd.

On the other hand I guess there can be other ways of filtering the mails 
do distinguish between those cases, so maybe it would be manageable?
