Re: [csswg-drafts] [css-fonts] should supported tech() be validated during parsing or loading? (#8793)

Yeah, that does make sense, but it seems to be conflicting with the other part of the spec that says:

> If a component value is parsed correctly and is of a [font format](https://www.w3.org/TR/css-fonts-4/#font-format-definitions) or [font tech](https://www.w3.org/TR/css-fonts-4/#font-tech-definitions) that the UA supports, add it to the list of supported sources. If parsing a component value results in a parsing error or its format or tech are unsupported, do not add it to the list of supported sources.
> 
> If there are no supported entries at the end of this process, the value for the [src](https://www.w3.org/TR/css-fonts-4/#descdef-font-face-src) descriptor is a parse error.

This should be probably discussed by the CSSWG.
