 lomiri issue is gone when building against -release component (with -proposed disabled). So it's not a blocker for the current transition.
 But the lomiri-ui-toolkit failure is reproducible in -release too. (re @mitya57: @mariogrip @fredldotme Hi again!
 We have more problems:
 1. lomiri-ui-toolkit test failures:
 FAIL!  : tst_UCUnits::gridUnitEnvironmentVariable() Compared doubles are not the same (fuzzy compare)
    Actual   (units.gridUnit()): 8
    Expected (11.0)            : 11
    Loc: [tst_units.cpp(48)]
 2. lomiri build failure:
 In file included from /<<PKGBUILDDIR>>/obj-powerpc64le-linux-gnu/tests/uqmlscene/uqmlscene_autogen/VNU7RW3YIC/moc_DebuggingController.cpp:10,
