Discrepancies between i386 port list and package list

Hello,

I'm currently daily-driving a 2008 i386 machine on
-current. Earlier this month, I tried out ungoogled-chromium,
which was available as a package at the time. I've
tried again today, and though the ports tree still
lists i386 as a valid platform, the different mirrors
I've tried do not provide ungoogled-chromium as a
package. The same appears to be true for pandoc,
and chromium: listed in ports as a valid target, but
not available as a package.

Is this due to a change of policy on i386 packages
which I've missed? Is this a known issue?

Kind regards,
Elie Le Vaillant
