Actually, now I'm thinking an even earlier version (from bug#49860) had
the most sensible approach for per-network SASL settings all along, and
that's simply recognizing `:user' and `:password' symbols as values for
`erc-sasl-user' and `erc-sasl-password' (possibly even as defaults). The
module then just uses whatever's stored in `erc-session-username' and
`erc-session-password' (and obviously inhibits the sending of a server
password).

Given the other realization above, I guess it's no surprise that I've
again flip-flopped on mentioning let-binding and have reverted to the
opinion that we shouldn't officially commit to local modules at all and
should minimize advertising their presence and behavior until we've
arrived at a workable solution for granular (network/nick/channel-aware)
user options.
