For many of my sets I've made a spreadsheet that's a simple grid labeled 0-9 across the top and 0- whatever preceeding digits are required for the set down the left column. Sort of an electronic checklist.
I've done the same with the superset spreadsheet for T206, stripped out the content and I use it as a checklist.
Neither is as elaborate as what you're looking for, but serves fairly well as a checklist. I haven't figured out a good way of handling variations, ones that affect an entire set I simply make a second page.
I've considered for a while making a sort of looseleaf version of the card encyclopedia. But with more detail for each set, and probably no pricing. But as Rich has mentioned, it's a vast amount of work. Hence the looseleaf, people could get just the sections they want, most wouldn't need updating soon if ever as long as pricing wasn't a primary feature.
