First know that this will never show up on the Downloads page, and I am *not* suggesting that it should
I'm not saying that, I'm saying for general download, wherever it may be. Rules compilations are a "no no".
In effect, it will end up being treated as a compendium of house rules, even though it is intended for a different kind of purpose.
This document has no "house rules" or rules for "how I run it"
House rules are needed if you are going to present the file as a compendium of house rules... a rules compendium without new rules is just a rules compendium unless you present it as a "rules addendum for playing in X world/campaign" which should include info about said world or campaign.
But, I don't understand this concern about the "a la carte" structure. Whether these are presented as a single file or multiple files, the contents are, by the very nature of Basic Fantasy itself, "a la carte". No one can force a GM to include or not include something irrespective of whether things are stored in a single file or multiple files. It doesn't change or alter that property of the game. In fact, it is impossible for this file to alter that property of the game.
It has been spoken before, and the common consensus is that any rule compilation could be taken as "official", "recommended", "the best of", and we try to avoid that.
There are lots of alternative rules across the forum, putting a compilation of some of them may be taken as "this is the best here, no need for further search".
Everything on the Downloads page is, by definition and literal positioning, given higher priority and prestige than anything on the Showcase page.
This proves my point above. That's a misconception of the Download page, Solo himself avoids giving "priority" to thing, the files on the Download page are there because that was the place where everything was place for download, the creation of the Workshop came later, and even later than that the Showcase was born.
Those are "Legacy/Historical", not "better because they are on the Download page"
It was talked years ago above removing the supplements from the Download page, but if Solo choose not to do it he surely had a point besides "they are better than yours"
