Doh, I fully expected I lied that it's going to be a one-liner. @phadej: is that all you need?

[phadej]

@Mikolaj yes. You'll make me very happy if you'll be able to squeeze that into Cabal-3.6.1.0 and that into GHC-9.2, but I'll probably survive even if it doesn't make there.

[Mikolaj]

I will try squeezing. Not sure about GHC-9.2, you'd need to ask them hairy GHC haxors.

[phadej]

It will be fine if it's bundled with GHC-9.2.2 (I doubt 9.2.1 will be the last in series), i.e. if you make Cabal-3.6.1 release once it accumulates enough backports and before GHC-9.2.2

[Mikolaj]

Sounds plausible.

@Mergifyio: backport 3.6

[Mikolaj]

Doh.

@Mergifyio backport 3.6

[mergify]

Command backport 3.6: success

Backports have been created
