I feel like I’ve seen elsewhere that the argument there is that you often must have this optimisation working in algos that rely on it or you will get stack overflows. Having a keyword to force it then becomes a very useful thing, vs relying on hopes that future compiler versions and different arch targets will all discover the optimisation opportunity.

Having a way to guarantee TCO/TCE is essential for some cases, yes. GP's question, though, was why a keyword specifically and not a hypothetical attribute that effectively does the same thing.

A keyword seems nicer to me. I think the only reason to use attributes is to avoid the work of adding actual new syntax, but seeing as they've already done that...
