2.2 - Hypothetically, a more complex client might cache per network location and revive the cached entries when it returns to the network where it received them.

I think your reading of MAY/SHOULD is correct.  Using Alt-Svc itself is totally optional -- but if you choose to, this is when you SHOULD switch to a given alternative.

COMMENT:
----------------------------------------------------------------------

Just a few minor comments:

= Substantive =

- 2.2, last paragraph:

Why might a client choose not to to remove non-persistent alternatives from cache on a network change? (i.e., why not MUST)?

- 2.4, first 2 paragraphs:

These paragraphs seem to be equivalent to saying “Clients MAY use alternative services; also they SHOULD.”  Or is the intent that, if a client uses alternative services, it SHOULD do so under these conditions?

= Editorial =

- 2.3, first paragraph:
I find "MUST only" constructions to be confusing and sometimes ambiguous due to the implied NOT. I suggest making that explicit:
OLD
   A client MUST only use a TLS-based alternative service if the client also supports TLS Server Name Indication (SNI).
NEW
   A client MUST NOT use a TLS-based alternative service unless the client supports TLS Server Name Indication (SNI).
