That would be fine. We’re talking about the difference between Discourse warning you that your instance might stop working soon, and it just informing you that it has already stopped working (in the CLI) or failing to update via the GUI.
Warnings are less stressful than a broken installation (for the admin) and if they include a link to some basic triage then admins who don’t ignore the warnings may be able to resolve the issue themselves, rather than posting here on meta with “My instance is broken, what do I do?”
Some rough idea of the RAM footprint (over time) of the instance would be great, down at the bottom of /admin where it shows space. The way I see it there are a lot of support topics which resolve down to RAM and disk space problems - warnings might reduce how often people need support.
