Its common practice to publish a Known Issues List for software products. Just do a Google search on "known issues" to verify. Users can peruse the issues list before reporting a bug, it increases the transparency of WGT, (something called for many times), and provides positive feedback to users that those issues "we will look into" really were looked into and bugs reported via the game client are noted.
This has been suggested before and deemed a burden to maintain by a WGT admin. If you already have a prioritized list of problems how much of a burden can it be, on a weekly basis, to copy and paste an existing problem list, to a forum post titled "Known Issues with v 1.44.19"?
The benefits of publishing such a list should outweigh the effort spent when more than mere manhours is considered.
