Not really, no; that is mostly an internal detail, and might change in
the future.  However, it is worth noting that the current convention for
naming of '*.o' files have been in place for quite some time, and it's
unlikely that it will be changed without a good reason; even if it will
be changed, the change will be prominently announced in Automake's NEWS
file.

So, to sum up, I think you can (ab)use this particular Automake internal
quite safely, as long as you keep an eye on the Automake's NEWS file to
be forewarned of any change that would break your use case.
