I'm not sure I agree with that name. First, it's a contraction, which
doesn't look right. Second, it's a negative (which is a problem with
the original flag as well.)
Instead, I'd go with either "saveable" (default: TRUE) or "transient"
(default: FALSE). I'm leaning more towards the latter, though it
depends on what connotation you wish to imply.

There was/is a plan to support only one buddy list. Not sure how that
fits in with that function.

Instead of "don't reconnect", we should probably define something that
encodes the result of registration. Something along the lines of
"failed to register user", "registered and updated settings, please
reconnect", or "registered and using this connection to continue",

As I understand it, that check is a "Did we call
purple_connection_error[_reason] already?" test.
The code in the if is a "we'll try this for old servers that can't
identify themselves as old servers". So if we've already connected
using the new version and run into an error because a bad password or
something, then we don't need to run the code in the if. But if we
haven't fully connected, then as a last resort, we'll try the old
server code and see if it works.
I'm sure there's a better way to write the condition somehow.

I believe Gary suggested using his GPlugin code for that. You should
probably talk to him if you haven't already.
