Not in that discussion, no. However if you go back to the original referenced post there is at least some support. Steffen himself says (his emphasis):
I would NOT want this to be the default behaviour, but having this an
option could be a boon to people like my employer, who run Perl on
thousands of machines and capacity is as important as latency.
And later ...
And while I'm at it: You distribution people out there: Don't ship a
perl without taint support by default!
There were a few others in the Larry/Hippo camp back then including Tux and Reini. But perhaps I will badger the p5p echo chamber with my opinions again now so they don't think it is obsolete.
