I should correct myself here. My thinking was a wrong (I swear I'm feeling less smart without my Linux box). A month ago the nghttp2 package got updated from 1.49.0 to 1.50.0 that brought the new symbol nghttp2_option_set_no_rfc9113_leading_and_trailing_ws_validation. So for the cases I pointed out, where users didn't update their Tumbleweed systems and had a libnghttp2-14 version previous to 1.50.0, it makes sense Zypper throwing that error because libcurl4 requires libnghttp2.so.14()(64bit) provided by libnghttp2-14. I might be wrong here, but since libcurl4 is depending on a new symbol introduced by nghtt2 1.50.0, there should've been introduced a new check for that specific symbol in there configure script, something like [1].
