[Zope-CMF] Upgrade steps linked to profiles

[Martin Aspeli]

Hi,

Several months ago, I seem to recall a discussion that led me to
believe it's now possible to register a GenericSetup upgrade step that
runs an extension profile when invoked, instead of having to write a
Python handler with imperative code to perform the migration.

Now, I can't find any trace of this - was I imagining things?

If so, would this be useful functionality?
