Should "WIP" be removed from a heading in the "Syntax" chapter?

I'm just getting familiar with Pest, so I'm wondering...

Should "WIP" be removed from this heading?

## Operator precedence and grouping (WIP)

File: src/grammars/syntax.md

I'm guessing this feature is no longer a work in progress. The Git blame shows 7 years ago.

Potentially. I think the "WIP" didn't necessarily mean the feature was WIP, but more that the text was WIP. From a quick look, I guess this section doesn't e.g. mentione{, n}, e{n,}, e{m,n}, !e and &e; stack operations and perhaps the interactions with COMMENT / WHITESPACE rules.
But in principle it can be removed
