The docstring also says:

    Since nothing is \"always\" true, don't use 100 nor -100.

100 means that nothing will *ever* want to come later.  I.e. you claim
to be the one and only function that will ever deserve to always be the
last one on this hook, which is rather presumptuous, I think.

AFAICT the only thing that actually matters is that it should come after
`org-persist-gc`, so even just 0.01 would be good enough.  No need to
get anywhere near 100 (tho it would make sense to leave room for other
hooks that might need to come between `org-persist-gc` and
`org-persist-write-all`).  Also, I'd recommend you add a comment
explaining the constraints that were considered when choosing this depth
(e.g "Make sure it comes after `org-persist-gc`").
