Running @psalmphp on my tests code has been a good decision so far. Makes it far easier to keep tests updated. Automation for the win!
If people want PHP generics then someone should create an RFC for erased-at-runtime generics. Erased-at-runtime types in PHP would be an insurmountable language shift for some voters, but maybe there’s enough support to carry it through.
All the major static analysis tools would quickly adapt, and there’s precedent in Python, which added support for type-erased generics (without a bundled typechecker to accompany that change).

Wrote a @psalmphp plugin to ensure I'm marking classes as final properly. If a concrete class does need to be inherited you can mark it with an Attribute to suppress the error.

The literal-string type continues to do good work! It's now also supported in @phpstan (thx to @craigfrancis), which caught a SQL injection bug here: forum.nette.org/cs/35223-php…
New type just dropped: Psalm 4.8 supports a new literal-string type which you can use to prevent SQL-injection attacks: psalm.dev/r/55dec032b9

While most of the work on Psalm is about getting it understand your code right, there's a place for UI improvements as well.
There are several that are either already shipped or coming soon:
1. Psalm now linkifies files in supporting terminals (thanks to @gregorharlan)
