    # emerge -pv neovim                                                                                                                                                                   1

    These are the packages that would be merged, in order:

    Calculating dependencies... done!

    emerge: there are no ebuilds built with USE flags to satisfy "dev-lua/luv[lua_single_target_luajit(-)?,lua_single_target_lua5-1(-)?,lua_single_target_lua5-2(-)?]".
    !!! One of the following packages is required to complete your request:
    - app-editors/neovim-0.4.4-r100::gentoo (Change USE: -lua_single_target_lua5-1, this change violates use flag constraints defined by app-editors/neovim-0.4.4-r100: 'exactly-one-of ( lua_single_target_luajit lua_single_target_lua5-1 lua_single_target_lua5-2 )')
    (dependency required by "app-editors/neovim-0.4.4-r100::gentoo" [ebuild])
    (dependency required by "neovim" [argument])

    # emerge --info | grep -i lua                                                                                                                                                         1
    LUA_SINGLE_TARGET="lua5-1"
    LUA_TARGETS="lua5-1"
    USE="..." ... LUA_SINGLE_TARGET="lua5-1" LUA_TARGETS="lua5-1" ...
    USE_EXPAND="... LUA_SINGLE_TARGET LUA_TARGETS ..."

As far as I can see, only one is selected.
