### Please describe the problem.
I am yet to grasp what is "the best" or "legit" functioning here but I think it should be consistent between `git add` and `git annex add`, but we observe that on an ACL powered filesystem, `git add` commits **without executable bit set**, whenever `git-annex add` even if adding to git, results in **executable bit set**.
Gory details
```
(datalad) [f006rq8@discovery-01 ds-perms]$ cat .gitattributes
* annex.backend=MD5E
**/.git* annex.largefiles=nothing
* annex.largefiles=((mimeencoding=binary)and(largerthan=0))
(datalad) [f006rq8@discovery-01 ds-perms]$ git --version
git version 2.39.2
(datalad) [f006rq8@discovery-01 ds-perms]$ git annex version --raw; echo
10.20240831+git21-gd717e9aca0-1~ndall+1
(datalad) [f006rq8@discovery-01 ds-perms]$ echo text > by-git-add
(datalad) [f006rq8@discovery-01 ds-perms]$ echo text > by-git-annex-add
(datalad) [f006rq8@discovery-01 ds-perms]$ git add by-git-add
(datalad) [f006rq8@discovery-01 ds-perms]$ git annex add by-git-annex-add
add by-git-annex-add (non-large file; adding content to git repository) ok
(recording state in git...)
(datalad) [f006rq8@discovery-01 ds-perms]$ git commit -m 'added two files, one with git-annex, one with git'
[master 1ed76d5] added two files, one with git-annex, one with git
2 files changed, 2 insertions(+)
create mode 100644 by-git-add
create mode 100755 by-git-annex-add
```
So the git added one committed with mode 100644 whenever git-annex added -- with 100755.
Both files appear "identical" at POSIX or ACL level of permissions:
