their point is that the bar for sending reports in should be as low as possible

Why?

Look: The bottleneck is not the number of reported possible issues, but the time, attention, and sustainable workload for the GNOME maintainers and developers. Anything that minimizes the latter is good.

Also, if LLM tools really continue to improve a lot (which is doubtful IMO), a shitty, half-assed, inconplete, ill-described bug report of today that is not attended to, due to its deficit, is not lost: If the bug is real and persists, due to the proclaimed future advancements in LLM technology, maintainers will receive another much much better bug report which causes less work in a year or two. Since maintainer's work capacity is the real bottleneck, this is a clear win!
