Has there been any additional work or investigation regarding this issue?

Not really. I just noticed that my example module is much faster with Maven
3.6.0 (~14s) that 3.3.9 (~20s), same Enforcer version (3.something).
That's better but still way too slow.
For now I ended up with a dedicated plugin execution that can be skipped
individually. Far from ideal and certainly not a permanent solution but it
eases the pain a bit...

My team thinks it's an important issue, and may be able to contribute work
towards it.

Any help is appreciated!

> I noticed that DependencyConvergence can take up to 10 seconds or even more
> in modules with almost 300 direct and transitive dependencies (reported by
> {{dependency:tree}}).
> These modules are part of a JEE project based on JBoss EAP 6.4 which imports
> a couple of EAP BOMs. Unfortunately I am not allowed to share this project.
> I profiled the rule via VisualVM and these are the top 5 hotspots:
> !visualvm.PNG!
> The number of {{parseVersion}} calls seems excessive.
> See attached {{visualvm_settings.xml}} for reference.
