BlueprintCompilationManager breaks Custom Compilers

The full question is here:

But what do you think… i know this is a nicpick but on an engine that gives the faculties to “extend” and create plugins, custom compilation for blueprints is a must… specially on plugins that must create this to work (Like PaperZD in this case, that totally breaks when the compilation manager is turned on).

For the moment PaperZD (for 4.17) needs BlueprintCompilationManager turned off to work, because the “fast compile” ignores the custom IKismetCompilerInterface given… 4.16 and before, this works with no real issue.
