Regarding the footnote, if I use -T then taint mode is on and the qx// correctly makes the script die:

$ perl -TE 'say $^V; say qq/Taint mode: ${^TAINT}/; say qx/date/'
v5.34.0
Taint mode: 1
Insecure $ENV{PATH} while running with -T switch at -e line 1.
$

Similarly the results using system are also as expected:

$ perl -E 'say $^V; say qq/Taint mode: ${^TAINT}/; system q/date/'
v5.34.0
Taint mode: 0

$ perl -TE 'say $^V; say qq/Taint mode: ${^TAINT}/; system q/date/'
v5.34.0
Taint mode: 1
Insecure $ENV{PATH} while running with -T switch at -e line 1.
$

In case it is unclear, I am running these on a non-MSWin32 system.
