My take on all this is don't hold your breath for anything of significance to materialise on Parish Churchyards for the best part of 10 years. As for Municipal cemeteries someone is having a laugh, if they expect to get round those in under 15 years, and that may be a tad too ambitious and the project likely a non-starter.
I have not visited many Parish Churchyards (although my wife certainly has and indeed we can hardly visit anywhere -whether family connected or not - without her insistence on looking in on the local churchyard). So I have her first hand reports on the un-readability of grave stones, broken or missing kerbs and headstones or those totally hidden by undergrowth. Only a few pass muster with "what a lovely well kept churchyard", and quite make her day.
On the other hand -and strictly limited to Birmingham - where of the 26 listed Cemeteries I have visited the 6 main Municipal ones over the years but would only claim fair knowledge of one, good of another and the 3rd almost intimately as that is the one most visited. As good as the Municipal records may be - to use a Brummie saying "fair to middling" - by the time you have been given instructions from the Cemetery site office (if lucky enough to find them open or staffed) to take the West path, 3rd avenue to the right, 7th row, 4th grave along (or something very similar) one ends up often disappointed at the dilapidated stonework found and unreadable name entries. This experience serves as an indicator of what would befall others trying to document Municipal Cemeteries throughout the country.
Unless they are to rely solely on Municipal and Parish records -such as they are - both projects will take an age to come to fruition hence to repeat what I said at the beginning of this narrative, expect nothing of significance before 2035-40. Until such time we must rely on what we have already via Family Search and its derivatives, and of course via many Family History websites.
Gravestones 100-150 years old are bad enough but Parish (particularly rural) graves are much older. Without the support of Records detailing who lies where, a seemingly impossible task. Of course I could be wrong but don't count on it.
