Any updates on OoS Products in PDF Form?

[Hawk]

I've been slowly buying up past COTG sets to fill my catalogue and today when looking I noticed more than ever there's a lot of "mainline" GWF COTG products listed as "out of stock". I know 2099, 2100, 2105 & 2106 are available in PDF form (and are missing entirely from the shop) but what about the other sets simply listed as Out of Stock? Are they available to be ordered on a case-by-case basis or are there any intentions to provide them in PDF form? It feels weird to have sets like 2119 and all the opening few years in B&W completely unavailable in print or PDF form. I understand that these sets aren't in high demand but that's why PDF would be the middle ground between Filsinger Games printing them directly right?
