AMD HD 8490 too old to fold?

They've tried 20 times to get a WU and nothing yet. It's in the supported list.

May be due to WS overloading and don't have enough bandwidth to send WUs to folders.
Just gotta wait a little.

The 8490 was supported until last yeas when the last GPU projects that only required Single Precision calculations finished. All of the current GPU projects require Double Precision for a small fraction of their calculations, so this card is no longer able to be used

AMD for its lower end cards often reused GPU chips from older series and did not provide DP support on them. In the HD 8000 series the 8500 and above cards do support DP.

No Double Precision floating point math, so it will not fold.

Is it reasonable to remove cards from the white list if there's not going to be projects for them? Or are they left on in case a new project comes along?

GPUs.txt is both a white list and a blacklist. certain columns should be 0 for black listed cards.

0x1002:0x6771:1:4:Caicos [Radeon R5 235X/HD 8490]

that is from https://apps.foldingathome.org/GPUs.txt

Maybe I just don't know how to read it?

After the projects that could be processed with GPUs supporting only SP finished, there was an open question whether some future smaller GPU projects would not require DP for part of their calculations. So editing and finding all of the entries to move them from the whitelist was pending waiting on that question. Then this came along...

As for the entry, first 2 fields are the manufacturer and device ID number, 3rd is 1 for AMD, 4th field indicates whether this AMD card supports DP. 4 there means no DP.
