The main reason is to reuse UI which was already implemented and tested, of
course. The second reason is that sometimes the standard UI provided by Windows
Installer was "good enough" to get the job done. Sometimes I don't need any
fancy UI features, nor I want to drag WPF dependencies, nor I want to get back
to MFC or plain Win32 API writing UI for my installer. <UI /> element did the
trick for me in a declarative way. I don't expect the standard bootstrapper dll
from WiX will be that customizable in a near future and it will still keep
depending on WPF even after.
Please, don't get me wrong, I'm still huge fan of WiX and I do understand the
original idea behind the Burn. Of course, I'll roll up my sleeves and give it a
try writing burn-driven bootstrapper, but for now it's sometimes good to have
an option to use a "dumb" chainer.

It's more like a selector, not a chainer. Installing only one msi from a set
according to a running environment (OS version, platform etc.), so user will
not see a bunch of popping-up windows installers, but only one. Yes, maybe it's
still a variation of the first scenario.
