It is a valid concern.

When a bug is found just after a major release .0, we must wait the next
major release to get it fixed in a release. I find it frustrating.
My thought is that the stable branch should help between two major releases.
If not releasing .1 between two major releases, we could at least
update the branch more regularly. It is currently a burst 2 weeks
before releasing the stable version, i.e. after the new major release
which already contains all the new fixes.
Some companies do not rely on the stable branches for the support of their
customers because the patches are applied too late. It is a pity.
It is OK that companies have their own backport with different risks
and priorities considerations. But we should try to have a common
community basis of backports without waiting 3 months.
The other concern is how to spread the validation efforts of the
main and stable releases over the year without overlaps.
