Oh no, absolutely not - as far as we can avoid google services it should be done - an android runtime is brilliant and gives the possibility to work around missing apps with android ones - I know not all are running without play services but that shouldn't encourage people to install them - the point for BlackBerry and Sailfish is running apps without that stuff - if you tend to install playstore, playservices or more (like openGapps on lineage or another custom Rom) - you could even use Android from the beginning ...
