User:Hijiri88/Proposal:Permanent full protection for process subpages

I have noticed somehing of a problem in the last few weeks. A number of process pages (WP:RM and WP:GAR among them) depend on transcluded subpages. The main process pages have hundreds of watchers, but the subpages have almost no one watching them. As a result, unilateral changes can go months or years without being noticed, or at least without being questioned. Given that the instructions included in these process subpages are meant to be (or at least are) taken as authoritative, care should be taken that they are in line our core policies.

I am almost certain that these unilateral changes were made in good faith, but since such changes should not generally be made without either prior community consensus or some way of determining that a significant portion of the community tacitly approved of the changes, I would like to propose either one of the following:
 * 1) Permanent full protection for all process subpages;
 * 2) Merging process subpages into their respective main process pages.

The former would prevent the pages from being edited by non-admins without prior discussion/consensus, while the latter would at least mean that the 1,580 editors watching RM and the 251 editors watching GAR would be notified when changes are made.

I am drafting this in my userspace because I am completely ignorant ignorant history merge (or whatever it is called) and almost as unfamiliar with the precedents for permanent full protection of pages. (I know the latter is used on some Wikia projects that are stricter than we are.) I would therefore like input on whether the above are the two best solutions for the problem, or are even feasible. I also am not 100% certain that users with a main page on their watchlists are not notified when a subpage is edited: neither WP:WATCHLIST nor WP:SUBPAGE apparently specify this either way, and my assumption that they are not notified is based on my being apparently able to watchlist them independently of each other.
