Coincidence or not, I just started checking this critical vulnerability:

https://nvd.nist.gov/vuln/detail/CVE-2026-8924

And it is directly related to libpsl. I presumed that having it disabled (by default or not) would make oe-core's version of curl (e.g. in Scarthgap and Kirkstone) not affected. In fact, I checked if the parts of the code inside USE_LIBPSL ifdef blocks is built or not (it isn't), and in do_configure logs:

curl version:     7.82.0
SSL:              enabled (OpenSSL v3+)
SSH:              no      (--with-{libssh,libssh2})

I'm not sure yet if this is a premature conclusion of mine, but I'd still want to give this heads-up, considered you added this option to PACKAGECONFIG in your second patch.
