microperl is basically still Perl5, except without the system specific configuration and likely without dynamic extensions (XS). See README.micro as included with the Perl tarball.

I'm not sure what modifications on the language level are worth to be made to microperl that wouldn't be the same if made to Perl5, as they share the same source code.

If you're looking to cut features from Perl (5), for example cutting away tie (thus giving up support for DBI), you can do that with perl in the same manner as with microperl, and it's likely just the same files that you modify. I think that microperl, or at least miniperl are (much) faster to build, so if you're modifying Perl internals, at least during the development stage, building one of the smaller Perls reduces your waiting cycle.
