There have been reports that 1.16 Experimental has indeed addressed script restrictions once again. I have seen one reported success from a server owner that initially had issues with 1.15, but 1.16 EXP allowed execution of their desired modset without error.

Disregard the above modlist, it is not relevant as the issue I was encountering was due to two admin mods being loaded at the same time hogging a lot of script room.

Ran into this issue again, I tried adding vehicles to my live server and encountered #initglobals.
I built a test server copying 1/1 including load order and all mods and the test server did not encounter #initglobals and was able to run 14 vehicle mods ontop of the live mod list...

Following.
