can i remove 1.54.0 from the rust version matrix? also not sure about the crater ci error https://github.com/slint-ui/document-features/actions/runs/11755663862/job/32754124105?pr=28#step:5:137, since i still see the document-features flag here https://github.com/palfrey/serial_test/blob/3ac9744b019bee996c4d44afc72a0b1af8be1809/serial_test/Cargo.toml#L18

Indeed, the crater error seems to be unrelated.
But let's try to keep the MSRV to a low value. So please revert the use of then_some
