The rectifier diodes will shave off a bit, but a lightly loaded AC transformer will output more than 12 V AC, so yeah, this isn’t good.

(e.g. [this one](https://www.block.eu/en_EN/productversion/vcm-36112/) that I was looking at the other day for a project has a “No-load voltage factor” of 1.11, so would peak just under 19 V, ignoring the diode drop).
