Text.Printf when built with base < 4.13, and it would define

build-depends line. However, people really shouldn't be using

Ok, but what does this effectively achieve?<br>
<br>
Text.Printf is an API that has been extremely stable and
doesn't<br>
significant evolve anymore; I don't think it has contributed
to major<br>
ver bumps in recent times, nor is it likely to. So I don't see
much of a<br>
compelling benefit in doing so. The effect I'd expect if we do
this is<br>
that `Text.Printf` will be reached for less (which some might
argue to<br>
be a desirable effect -- but you're effectively pushing this
API to a<br>
path of slow legacy death due to reduced discoverability,
IMO), as the<br>
convenience of using it is reduced by requiring adding and
maintaining<br>
an additional `build-depends` line to your package
descriptions, as well<br>
as having to deal with the subtly tricky business of handling
the<br>
migration path pre/post-split (c.f. the `network-bsd` split
currently<br>
being in progress).<br>
<br>
Btw, a related extremely stable API in base I could think of
which<br>
people might argue doesn't belong into `base` either is maybe<br>
`System.Console.GetOpt`; would you argue to split that off as
well?<br>
