One issue I envision is when unsafe variable dialogue is being
displayed. If font-locking is not setup prior to that, Emacs will try to
fontify the visible part of buffer when displaying the dialogue and
later font-lock settings may not fully apply.
See https://list.orgmode.org/orgmode/878ro8kqwv.fsf@localhost/T/#u

Indeed. However, a lot more things in Org mode depend on user
customizations. For example, buffer-invisibility-spec may be changed
depending on user settings, including settings defined in file-local
variables.

I was mostly asking if you are aware about any gotchas.
As I stated above, there is at least one gotcha with early fontification
when unsafe variable dialogue is being shown.
