[wix-devs] 3703 - Add ability to change DisplayInternalUI at runtime

[Bob Arnson]

Right. The BA could control the UI level completely, the engine would have no knowledge of it, WixStdBA would support the equivalent of DisplayInternalUI, and a theoretical future BA could offer more control.

Subject: [wix-devs] 3703 - Add ability to change DisplayInternalUI at runtime

There's been some recent interest for
https://github.com/wixtoolset/issues/issues/3703. During one of our meetings, we had discussed pulling DisplayInternalUI out of the engine in
v4 but unfortunately I think our discussion was after we stopped recording.
I didn't take any notes at the time so I don't remember any details, but I think we were talking about giving the BA the ability to control the UI level, removing the bal:DisplayInternalUI attribute, and creating another built-in BA that would support this new functionality. I think the motivation for these changes was that there are very old bugs with DisplayInternalUI that no one has shown interest in fixing

Based on what I remember, I don't think we were planning on doing the simple change of allowing the BA to directly change DisplayInternalUI like in https://github.com/wixtoolset/wix3/pull/502?
