I have the feeling some classic users want not pay any cent to upgrate their hardware.
True, but there are also people who want chipset+680x0. People who aren't interested in PPC+GFX card. I'm one of them. If I want more speed then I'll just use my peecee. If I want better graphics then I'll just use my peecee. And so on.
I'd rather spend money on other upgrades. Things such as more memory, mouse and keyboard controllers, network cards, etc. Even if a good Amiga GFX card only costs 5 bucks, I wouldn't be interested in using it and I would only buy it to make it available to people who are interested in it.
Chipset+680x0 can do more than is shown today, but it's just not so easy to get it done

2. Disable requirement of true type fonts so that it would work with AGA
TrueType fonts can work with AGA. They can in fact work with C64 bitmaps if you wanted to.
