Does removing Stagnant Quality profiles help?
Does removing of deprecated rules help?
How could this be achieved for Java Language?

Hi,

Welcome to the community!

These are interesting questions.

For stagnant Quality Profiles, I guess you mean ones that aren’t in use anymore? There won’t be any performance benefits from removing them, but from a tidiness and understandability perspective, I’d say removing them would be a good idea.

For deprecated rules, yes, you should remove them. When we deprecate a rule it’s either because we don’t think it’s a good idea anymore or because we’ve replaced it with a better version.

For both of these things this would be manual work.

How do we remove deprecated rules and stagnant quality profiles?

Hi,

For non-built-in, non-default profiles, if you have permissions to do so, you’ll see a Delete option in the profile’s cog menu.

For rules, you can delete them from your profiles, but not from the instance itself.

Can we do that for built-in and default profiles?

No. That’s why I qualified my statement.
