Ultimately, the question here is as simple as whether the DAO should honour its obligations. The compensation guidelines were set prior to the most recent elections, as required by @AvsA’s successful proposal in the previous term. Nominees very reasonably believed that the DAO would honour these recommendations when putting themselves forward, and factored the compensation into their decision to serve.
If the DAO now wishes to renege on the agreed compensation because the token price has increased in the meantime, it is able to do so - but delegates should think carefully about the precedent this sets, and whether we will be able to attract qualified stewards if they are faced with the possibility that the DAO will alter the deal retrospectively after they have accepted the position. I doubt anyone here would be raising strenuous objections if the price of the token had collapsed, so this amounts to expecting the stewards to accept the downside risk but not the upside risk, too.
Delegates can put forward proposals to fix steward compensation for future terms - and I think that this would be a good revision, as it would entail getting explicit buy-in from the whole DAO for future compensation packages. I would suggest requesting that the current MG WG stewards put forward a new proposal, and then voting on it explicitly as a social proposal, as well as changing the bylaws to require that all future compensation changes be handled in the same manner. The stewards can compose their proposal based on the feedback here and elsewhere from delegates.
As outlined above, though, I believe that delegates should think extremely carefully before Darth-Vadering the compensation that stewards relied on when accepting the position, and I would beg @Griff @James and others who have expressed an intention to vote against this to reconsider their positions.
