That's a feature ;)

The x bit can easily get lost on kernel scripts.  For example, if
someone upgrades their kernel with patch(1) and the patch adds or
renames the script, the x bit gets lost.

If we were to set the x bit for the subset of people who get their
scripts direct from a git repository then those people might write and
distribute tools which fail when used by people who have lost their x
bit.  I've seen this happen at least once before.
