Yes, #2 IS painful. Even Dialyzer could be bitten by it;
by users who want to analyze their system but don't want
to re-compile.

I suggest that erl_parse could start to produce the new format
for record definitions, but that any Erlang module that interprets
the format (erl_expand_records and others) convert from the old
format to the new on the fly. In a future release, support for the
old format could be dropped.
