Yes, this is one of the major reasons that we registered our own TLDs. It's definitely not a secret.

Don't forget, .google is far from the only closed TLD we have, too.
Would Google entertain supporting something like .local.dev for this purpose, used only within a single organization and without reverse-lookup supported?
If not, is there a better alternative that also maintains the aesthetics as well as the similarity with production domain names?
We use real domain names for all of our dev servers on my team. They happen to be .co domain names, not our own TLDs, because of a chicken-and-the-egg problem.
