This isn't necessary.  Window managers place frames situated within
non-current virtual desktops in the Iconic state by custom, and such
frames are accounted invisible by Emacs.

Unless i3 contravenes this established practice, such explicit
comparison is unnecessary and expensive.

My point is, not enjoying the patronage of those protocols' developers,
we are in no position to maintain up-to-date support for the many
versions that are undoubtedly present on our user's computers.

Please see above.
