How reliable mkisofs' UDF support is?

["Daniel M." <quantera@gmail.com>]

Hello,

Mkisofs's manpage says that it's UDF support is in alpha status, and that "there
are many pitfalls with the current implementation". What does that actually
means  from user's perspective - does that means that one day CDs/DVDs which
were burnt from images made by mkisofs with '-udf' option on may become
unreadable (maybe because of the lack of compliance with the standard), that
data can become corrupted more easily or something equally bad?

Daniel.
