Well, at the very least:

How can I pass a UTF-8 string to AppendStr in the Unicode RTL?
The Example62 from the docs will no longer compile =D
That depends on what the compiler will do for you :-)
2> TStrings will be in a different encoding from the rest of the LCL,
this will surely be very nasty.
MyForm.Caption := MyStrings.Strings[9]; and you get an encoding conversion...
That will always be the case, even if we decided for UTF-16.
Basically it will be a salad of automatic conversions done by the compiler...
This will be so in each case where different codepages or encodings are used.
3> FileOpen(MyForm.Caption, whatever_mode);
You get first utf-8 -> utf-16 to call FileOpen and then FileOpen does
utf-16->utf-8 on UNIXes
Once more, why do you think so ?
In each case:
1. It will be messy whatever we do.
Thinking there is an easy migration path is wishful thinking.
2. Backwards compatibility is a big concern.
Code that compiled and worked should compile and work.
Michael.
