I wonder why this was done like this in the first place 😅
Did you test this and confirm that it still works? If yes, this can be merged. Thanks for noticing! :-)

[ghost]

Yeah it strangely works ¯\_(ツ)_/¯ I firstly even expected it to not work. And I was checking out to something like ~v0.17.0 and didn't found any other usage even there but I didn't trace to the roots.

I sometimes describe myself as semantic spider (who crawls project(s) and finds some nitty gritty details which for some reason accidentally still alive. Very stupid spider though)

Well it's nice you found this nonetheless, will make translator's life easier :-)
