I take your point, however whether we like it or not, we have to move with the times. For many of us searching, the 1850 is the start point for reliable* BMD records, prior to this we had to rely on the church, and as its influence has waned considerably, whilst my youth might trail yours by only 10 years or so, we both know the deference and respect for authority has diminished and is hardly likely to return. Looking at the various iniquities of the past, I don't think this is a bad thing - however, I still would not accuse someone who's marriage was formalised by a Warrant as 'Irregular'. There are some who deem the new 'Civil Partnerships' as being on an equal footing, however if there is a legitimate paper trail, I doubt genealogy hunters in the future will care either way!
