Update 2021-02-26:
While this still has no tangible name, currently running under the working name SKAL (which was previously ELUR and permutations thereof, including LURE, even though it won't lure anyone), the patching launcher itself is taking form. The plug-in system will be post-poned to a later version, because currently it is very fragile and the built-in functionality ought to be enough for anybody.
The skin support, as opposed to ROCred, will use PNG rather than BMP. While magenta will still serve as transparent color and alpha-blending support is absent, at least the skin files will be smaller. Like pre-2.4.5 RSU plug-ins PANTEXT and PANHTML, the patch news will be built-in and use the IE WebView for HTML patch news (how that works out on Win10 will be left for community feedback). The major difference is, that you can summon multiple patch news (as much as Windows allows), for example for providing seem-less interactive controls to the interface, like server status. As in ROCred the amount of buttons is also limited by available memory only.
The patch part builds on top of the RSU4 framework and the RSULIB3 library so you get the same performance, but with multi-GRF support. RGZ support is planned in the initial version. Later versions may introduce support for ZIP, RAR, 7Z/LZMA, either built-in, or as plug-ins.
The launcher part remains essentially unchanged to ROCred.
How configuration will be provided is not yet decided, options are three. Embedded into the plauncher (AV vendors hate this), a separate file or files, or all resources stored in a remote location.
Merging is still in progress, the rsu codebase is messy, so it will take some time.

Someone give me a full week hikikomori mode without disturbance and I can release it...
Update 2017-08-05:
People who will want to extend the functionality of the patncher, can start learning COM. The plug-in will have to establish communication with a call like this:
hr = CoGetClassObject(CLSID_PluginServiceProvider, CLSCTX_INPROC_SERVER, NULL, IID_IClassFactory, &lpServiceProvider);
Update 2020-08-18:
Obviously no one will read this, and no one will dare to make a necro-post in response to this. Since I have nothing to do for a week, I'm finishing that thing. Things are coming along quite well so far. The updater part is written from scratch, since the RSU code-base is too outdated. Not sure about the ROCred part, there is currently no UI. Oh yeah, there is no name either...
