No postscreen(8) has nothing to do with it, it just defaults to whatever
smtpd(8) defaults to. The real issue is that you have (whether as a
compiled in default, or in fact in main.cf) a non-empty setting for:
smtpd_discard_ehlo_keywords = chunking
if that's also reported by "postconf -d", then whoever compiled your Postfix
package decided to change the upstream default. If you don't like that choice
you can set an explicit empty value in main.cf and complain to your package
maintainers:
smtpd_discard_ehlo_keywords =
