Some users (especially those that upgrade from Colibri skin) prefer: - to have the logo in the header area or - provide multiple logos (for subwikis) or - have a logo and a background-image as header, etc. I created the issue because there was a bug with the setting of the value. Now the exposure in the Theme Editor was mostly a suggestion. The main problem is determining how advanced this usecase is and how used/needed it is. Currently I don't think is very needed since we didn't had someone creating an issue and requesting to change this from the Theme (as a normal user). But fixing the bug and making sure developers can change this is needed. Regarding the UIXP, the value of displayPageHeader is still needed, since if you add a custom header that contains the logo, you might want to disable the current logo from navbar. This variable controls that. So, although I suggested to add it to the Editor, I am not sure about this: because we should expose mostly the recommended/default values (not compatibility ones); the use case is kind of limited, but should be changed by a developer; it will increase the testing time / values in order to support the use case.
