A bit slow on this - sorry..
I can't find any information that backs up your 'ones build before 2001 do not have a life limit' statement - are you able to share? I'd love to find some definitive info on this, as my rigger won't back my immaculate 20 year old chute.
The manual here clearly states that softie chutes have a 20 year service life (see 1.4) :
