This was a hack to make the IsaMakefile (and usedir) correctly depend on the release image instead of a developer image (needed only for editors who need to check against release versions). This was more relevant in the days where the release heap directory the same as for devel versions, but still mildly useful afterwards.

If I understand the new build system correctly, this is now irrelevant and can be ignored.
