I think anyone tech savvy enough to be using Pages should also be savvy enough to understand[0] why the A records can't (realistically) be as fast as the CNAME alternative, and understand if you make it de facto redundant (i.e. available, but not actively encouraged or supported).

I think it's fantastic that you provide apex support for everyone even though it must be exponentially harder to do that just providing CNAMEs, but if you're upfront about the limitations the only people who are going to complain are the type of people you don't want to be listening to anyway.

[0] I mean that in the sense that they'll comprehend the explanation, not that they'll grok it inherently.
