You'd be fine.  I tried to make this clear by saying:
Some things to keep in mind:
  * Darcs 2.4.4 is perfectly backwards compatible with older darcs and older
repos.

In particular, the manual[1] says:
The --upgrade option for darcs optimize performs an inplace upgrade of your
repository to the latest compatible format. Right now means that darcs 1
old-fashioned repositories will be upgraded to darcs-1 hashed repositories
(and notably, not to darcs 2 repositories as that would not be compatible;
see darcs convert).
