Style and upgrade "Briefly unavailable for scheduled maintenance. Check back in a minute." page

[tw2113]

While ideally it would not be shown except briefly, the current display of the "Briefly unavailable for scheduled maintenance. Check back in a minute." feels very unprofessional and generic. Perhaps we should consider dropping the message into some output similar to the readme.html file.

Thoughts?
Concerns?

Looks like ​maintenance check happens too early to utilize wp_die(), but perhaps some basic styles could be borrowed from its template?

The template was deliberately kept minimal and non-WordPressy for the same reason which we removed the styling from the database-is-down message - There's no reason to connect either of those "errors" to WordPress directly, once upon a time people would see the database-is-down message and blame WordPress, that happens a little less now, as it's a little more obvious where the problem lies.

When the total upgrade time of WordPress is generally sub-20-seconds (which means maintenance mode will be even less) and background-minor-updates average something much faster, sub-10-seconds I'm not sure too much effort should be put into the design of that screen.

Perhaps just a gray background and centered text, keep the WP logo off the top. I agree with keeping it minimal, but a tiny bit of styling wouldn't hurt.

No hard feelings if wontfix, also.

Replying to dd32:

The database-is-down message makes sense to keep minimal, as that could be for any number of reasons not related to WordPress. However, maintenance mode is a WordPress construct, so using WordPress styling seems right here.
