There is a ceiling, in that too large a list will blow out the
35000-octet minimum packet size limit.  But it's a long way from 256.

My own implementation offers

which is just a hair under 1K of algorithm names, and, while I haven't
tested it extensively against a wide variety of implementations, I
haven't run into anything that either objects or breaks in response to
that.

That is my own take on it.
