deterministic build failures due to Jabel

[vbarua]

Periodically, Jabel does not appear to trigger correctly during builds and results in builds failing, locally and in CI, due to errors related to features it should be transforming.

See #193 (comment) for an example

The pull request I made on-top of the prior change builds fine, even though the code that was causing the error has been updated.
#194

I guess this is now resolved via #433 which removes Jabel.
