See also bug #68347, though I don't think it can be reasonably argued that this version is not a bug either.

Well, we can't fix that without breaking valid code, and the
"feature" behaves as advertized anyway[1].  So I'm going to close
this as not a bug.

This is also how parser is behaving with INI_SCANNER_RAW which is at least unexpected. In that mode I feel everything should be parsed as string. And also this probably wouldn't be a breaking change since with "on" in key, function will fail all together. Unless obviously someone is relaying on having error.

Ugh, I thought that wouldn't affect INI_SCANNER_RAW, but obviously
it does, and it is even documented.  And yes, you're right, fixing
this would not really cause a BC break.
