Yes, would nice, we also can't update our lib without this

[tispratik]

+1. Can we merge it?

[ddon]

Would be really nice!

[mberrueta-cn]

need it too

[optikfluffel]

@ddon @mberrueta-cn I'm curious why you need this PR so badly. Is there anything preventing you from doing {:gettext, "~> 1.0", override: true} as a workaround for now?

[SebastianMueller87]

@bitwalker have you already seen this?

[lwld]

@optikfluffel the answer is in your question: it's a workaround. Not everybody wants to have workarounds in their code. Not every dev might be sure that the override is safe in this case.

The question should be "Is there anything preventing this from being merged and released?", not the other way round.
