Since Babel 8 should be released relatively soon, I am not sure we should already add support for this breaking change in v7.15.

Should we continue these changes under the BABEL_8_BREAKING flag like the those?

[fedeci]

Maybe yes, but what benefits would that bring? We only put more effort in handling a double source of truth for probably a couple of months(?)

[nicolo-ribaudo]

If you prefer we can keep this as-is, and wait merging it until Babel 8.

[fedeci]

Yes, I think it would be more sustainable.
Instead, this is a bug that should be addressed in v7.15, even if it may be a breaking change for someone.

[hzoo]

Ok I just wanted too to check we were ok with it, it's a pretty small scope change otherwise? It wouldn't be great if it broke in a dep that caused issues for people but that seems unlikely?

[fedeci]

I'm not sure if that small change broke the entire CRA e2e. I'll investigate tomorrow.
