If you don't notice any issue as it stands you can leave well enough alone, however you are right to note that in general this can break things and should not become common practice.
If you start to have issues then I am afraid the only resolution is to uninstall everything and start a fresh with play first apps second. Maybe do a backup of that particular profile excluding Play Services and just restore what you can after un and installing them again.
To prevent it in the future: Longpress on the update entry, then hit add to blacklist
