I believe your deptree is broken. If your gentoo repo is new enough to have the eclass change that causes this error, you should also have qtcore-5.7.1-r2 which depends on dev-libs/double-conversion.
qtsql already depends on ~dev-qt/qtcore-${PV}, so qtcore-5.7.1-r2 should be pulled into the depgraph if you're emerging qtsql.

I have also hit this error when emerging dev-qt/qtxml-5.7.1.

A qtcore version installed on this system is dev-qt/qtcore-5.7.1.
The qtxml-5.7.1 ebuild depends only on ~dev-qt/qtcore-5.7.1 so this dependency
is satisfied by this qtcore version.

From what I can see there is no dependency on >=dev-qt/qtcore-5.7.1-r2 anywhere
in qtxml or eclass.

Turns out I was incorrect. '~' means *any* revision, not the highest available revision. Therefore a dependency on ~dev-qt/qtcore-${PV} doesn't guarantee that the latest revision is pulled into the depgraph.

Can we consider this obsolete after all this time?

Close enough, or at the very least it will be when 5.9 goes stable.
