Actually it might.
I think that what happened was this:
in the early days of heartbeat, way back when,
source code got "batch tagged" with the license statement:
Most stuff got tagged with the LGPL 2.1.
Some time later, someone noticed that in some cases,
a "program" is not a "library", and tried to re-tag
e.g. "api_test.c" with the GPL 2,
but without properly taking the actual suggested GPL 2 stanza,
but by simply dropping "Lesser" and changing "library" to "software".
Both changes predate the GPLv3 by seven years.
>From there it propagated to ipfail.c and attrd.c, which both became
*the* template files to start from when writing daemons and extensions
using the API.
Developers quickly browse their "template",
their "auto-correct" filter reads "GPL 2",
which they are content with,
and in good faith they hack away.
I think it is safe to assume that any developer copying from there meant
to "stay in project" regarding the licensing.
So I move to change it to GPLv2+, for everything that is a "program",
and LGPLv2.1 for everything that may be viewed as a libraray.
At least that's how I will correct the wording in the
affected files in the heartbeat mercurial.
