This is just my personal opinion, but I do think that using
"initialization" is risky if it uses anything outside of the unit, and
hence you should minimise any inter-dependencies. If I had to suggest a
concrete workaround, it would be a initialisation routine that you call
manually or as part of an object constructor, although it ends up
requiring a bit more work for those who use the unit.
Sorry I can't be of much more help.

Have there been any changes to the initialization order of units in

I have a complex project with multiple units with initialization
section. And now
one of those units does not get initialized before it is used by the
initialization part of
an other unit. This worked at the beginning of the year!
It might be caused the fix for
https://bugs.freepascal.org/view.php?id=32352. Keep in mind that if
there are uses-cycles via the implementation section, the
initialisation
order of the involved units is undefined.
There it is again: my pet project: Why doesn't pascal allow circular
unit references (at least for classes, like forwards)!
I like pascal very much but this is the biggest annoyance!
You always have to work around this (put multiple classes in one
unit, create interface classes, ...). And now this:
I have such cycles, but it worked before.
I removed this cycles and it worked as expected.
Isn't there a way to force the order?
Why isn't it initialized first even if the unit is the first after
Forms in the program?
If there are uses-cycles via the implementation section why doesn't
fpc prioritize interface order?
Basically because of this:
