And, many DO plummet, with reduced control authority.
It is highly dependent on what kind of glider!
Don't assume...

That's why I recommend owners try at least one airport landing with the mast up,
and engine stopped, so they know what to expect if it happens to them. The 26E,
with the gear out and mast up, reminds me of landing a Blanik.

I've never had anyone flying the usual PIK, DG, ASH, and Ventus self-launchers
mention plummeting or reduced control authority to me, but I'm sure there must be
some like that. What gliders have this plummet/control authority problem, and how
bad is the plummet (same as half spoiler, full spoiler, etc), and reduction in
control?
