It is a documented feature that you "can use /Qt Assistant/ as the help 
viewer in your applications" 
(https://doc.qt.io/qt-5/qtassistant-index.html). There are commercial 
applications and open source applications relying on this for *user 
documenation*. The use of Qt Help tools outside Qt became fairly evident 
not so long ago when in Qt 5.12.0 a) qcollectiongenerator was 
(temporarily) removed in Qt 5.12.0, and b) Qt Assistant (temporarily) 
lost it is ability to show documentation from read-only locations 

For applications other than Qt Creator, increasing the size of Qt 
Assistant binaries might have a more significant effect. In the MinGW 
x64 build of my application, Qt Assistant (QTextBrowser), Qt5Help, 
Qt5Sql and the sqlite plugin account for app. 2.1 MB out of 54 MB binary 
files. Since the app is working with geospatial raster and vector data, 
also RAM is an issue for some users.

I would certainly appreciate improved HTML/CSS support in QTextBrowser 
(or a replacement). But I do not want to pull in the equivalent of a web 
browser with networking and javascript just for the purpose of 
displaying and printing static offline docs from the file system. Let 
alone the possibility to build for MinGW.
