Do you mean OpenStack developers, OpenStack customers, or OpenStack code?

OpenStack developers mostly say 'tenant', I'd say from my following of
the ML.

All the OpenStack users/operators/customers that I've interacted with,
say 'tenant'.

As far as code is concerned, I'm fine with any initiative to align the
Neutron code better with other OpenStack code - but only so long as this
is change that doesn't cause pain and loss of back-compatibility.  Even
the merge pain from this change may be substantial, let alone that from
API changes.

I'm not sure what you mean here.

Dariusz asked for feedback, and I believe it's valid and useful for me
to give my intuitive feedback without having to read up on the history

Also it seems likely to me that the fact that this work hasn't happened,
for two years, is a reflection of most people not really wanting it.  I
thought it might be helpful to get that out in the open.

That said, I did look at some of the history -

and noted a couple of points:

1. The text here twice says "multi-tenant isolation", not "multi-project

2. This whole renaming proposal apparently stems from an internal
confusion in keystone?
