I think that the market of users will decide. I assume the best of intention for the module author. The proof of it's usefulness (presumably due to it's tiny footprint) is that it will get used. In the case of HTTP::Tiny, it was used so heavily that it was rolled into core. Also note, there are ::Fast, ::PP (pure Perl), and ::XS traditions as well, for example: Class::Accessor::Fast, Date::Pcalc, JSON::PP/JSON::XS.
