Thanks for your feedback!
And there are far more votes for the related issue here too:
Integration with Skype Consumer is no longer under review, and officially planned.
Just look at Warren the decliner, chucking away like it's all a big joke.
Declining and ignoring this request forces staff to use personal Skype (consumer) accounts to communicate with contacts outside of O365.
Pestering clients to use guest access is not going to happen either.
Probably the votes to this topic will skyrocket once organsations are forced into Teams to discover a vital line of communication is missing.
