I wonder how much disk storage we are talking about?

For mobile stacks, such as Qt/Necessitas on Android the runtime needs to 
be downloaded over the air.   Depending on your connectivity a few 
megabytes can be a relatively big difference.   Also the phone internal 
storage space is often just few hundred megabytes, if that, so being 
conservative in disk usage is good for that too.

All in all, I think the impact on mobile devices will be bigger than 
elsewhere for having two engines.

Just my 2 cents,
