Jolla CEO Tomi Pienimäki went on record last month stating that devices will ship with its own app store partner, Yandex http://store.yandex.com I believe, not Google Play.

So apps consuming Play Services might work if a user was able to install the play services .apk, but I guess this would not be in a supported fashion.

Seems all very murky. Jolla claims full Android compatibility but I don't believe it has Android(™) compatibility. Would be a good developer FAQ.
