That's fair. I was aware of that, but I wasn't thinking of that use of the word when I read it, I thought of the other meaning of "seamless".

Seamless is a word with a specific meaning within the context of VMs.

The problem is it also has another specific meaning in the context of integrations in general: it means low fuss, minimal setup, no troubleshooting.

A different selection of words (windowless?) would have avoided this debate.
