Thanks for the suggestion ; that does solve the problem, tho' how anyone
could derive that info from the Portage output is quite beyond me :

root:570 ~> PYTHON_TARGETS="python3_6 python3_7" emerge -pv pycairo pygobject
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild     U  ] dev-python/pycairo-1.19.1::gentoo [1.18.2::gentoo]
USE="-doc -examples -test" PYTHON_TARGETS="(-pypy3) (-python2_7%*)
python3_6 python3_7 -python3_8 (-python3_9)" 201 KiB
[ebuild   R    ] dev-python/pygobject-3.34.0:3::gentoo
USE="cairo -examples -test"
PYTHON_TARGETS="-python2_7* python3_6 python3_7 -python3_8 (-python3_9)"
