This is probably a too-wild idea, but what I personally would love to see would be to adopt the extensions of Dr Andy White's BetaBASIC.
I wrote most of the Wikipedia article about BetaBASIC:

Even 40+ years later, it remains one of my favourite ever BASIC dialects. I did badly miss integer variables, but it was IMHO the most thoughtful and considered extension of Sinclair BASIC ever made.
I am a little sad that the SAM Coupé's BASIC, which Wright also wrote, has never had a FOSS clone.

If you still want to work on it, add sample code. I think that’s a must for a programming language page.
I see https://en.wikipedia.org/wiki/Sinclair_BASIC doesn’t, either but at least it has a list of commands. I still prefer sample code, though. It is the better way to present things, even though it will give an incomplete overview of capabilities.
