There are three sets of PMCs here:
1) Standard. These are compiled in to Parrot, you can guarantee they're there, can hard-code their PMC numbers, and don't need to do anything special to make sure the PMCs are available.
2) Library. These aren't compiled into Parrot, but are shipped as part of the standard library--to use them you need to look their PMC numbers up at runtime and will need to do a load_library somewhere before using them to actually load the PMC code for use.
3) Everything else. The stuff that doesn't get compiled into parrot or goes in the base library.
Things that go in category #1 are PMCs that are fundamental to parrot's working (stash PMCs, for example) or so basic and universal we want them everywhere. (Such as parrot's objects, or the PMC wrappers for the lower-level types)
Things that go in category #2 are PMCs that are useful and we don't want folks to have to bother rewriting (again, and again, and again) but don't want to burn memory and startup time on for everyone. The complex PMC would go here, for example, as would language-specific PMCs. (Tcl, Perl, Python, Ruby, etc)
Category 3 is CPaAN stuff, or ancillary libraries that we want to develop in tandem with parrot but not necessarily ship as part of the core distribution. (More complex math PMCs might go here, for example)
At the moment I'm concentrating on things for category #1, and will probably punt on everything else for now. When we've got more lists set up (Ask's working on it, so at some point we will have a compilers, standard library, and real perl6-internals list) we'll push the discussion to the standard library list, where it belongs.
As part of this, as we go along some of what is in classes/ will get moved to dynclasses/ and likely some of the stuff in ops/ will move to dynops/. (And some of the semi-op-ish things will end up in the standard library, like the backtick stuff probably ought)
