I think that approach would be better. A major version number change
is appropriate if I add a lot of functions to a package, even though
it may still be compatible with earlier releases.

But instead of "FALSE", I'd rather see the earliest compatible version
number listed.  For example, if 1.0, 2.0 and 2.1 are all compatible,
all versions could say

 BackwardsCompatibleTo:  1.0

If I had skipped upgrading to 2.0, I'd still know that 2.1 is
compatible with 1.0.  Similarly, if 2.0 was incompatible with 1.0,
this scheme would tell me that it was not safe to go directly from 1.0
to 2.1.
