Yes. And you don't want to keep long lists of all prefixes that you want to
have, so I think it is more for exceptions where there are clashes than for
mass transition to this scheme. To be honest I always found it annoying in
Delphi, and use old names and prefixes as much as possible.

But it does resolves problems like Lazarus currently (afaik) not installing FV
because units conflict. 

E.g. The conflicting units can get a prefix lcl. and
Lazarus automatically adds the prefix parameter for projects that use LCL.

Similarly for other packages that have very common names.

Only projects that really use both such packages will have to use the longer
form.
