Yes. I agree and I believe ALGAO are on to this? The precedent has already be set by the East Anglian guidelines. However, it is unlikely that any such document would set minimum percentages of trenching, and I would warn against this (as other have) as it could play into developers hands and make larger sample sizes difficult to argue for. A 'one size fits all' policy for evaluations just isn't sensible or desirable and approaches should be determined on a site by site basis. However, standards for recording, photography, surveying, archiving, reporting and so on, would be useful.
