A quarter of respondents thought the Department of Work and Pensions proposals to allow defined benefit schemes to self-certify for auto-enrolment would be unworkable, while a third disagreed.
Several respondents thought trustees of well-run schemes should be trusted to self-certify and welcomed any reduction in red tape.
"It stands to reason that if a DB scheme has survived this long it must be well-run," said one commentator. "What's wrong with allowing a well-run scheme to self-certify?"
Another contributor added: "Some people fear any reduction in bureaucracy. Surely it is only polite to be nice to DB schemes during their twilight years of protracted ill-health with only an eventual death in front of them."
But others worried about a potential lack of accountability. One contributor warned: "It is all very well and good to keep things in house but, when things go wrong, who is there to safeguard things? Remember Maxwell?"
This week's edition of Professional Pensions is out now.
The government is in talks with the UK and Irish pensions regulators over how to protect members of cross-border schemes in the event of a no-deal Brexit.
The equalisation of guaranteed minimum pensions (GMPs) is at least two years away from being completed, and could take longer than four years for some schemes, a poll has found.
The Pensions Regulator will consider if schemes should be required to have professional trustees and assess the case for greater regulation of administrators and system providers, PP can reveal.
