How experimental is OS X 64-Bit mode?

[Tiemo Hollmann TB]

Hello,

working with LC 8.1.1 I would like to prepare my programs for the next
future as long as possible. I wouldn't like to produce a new 64 Bit
standalone for all of my programs in a year, if in a year Apple makes 64 Bit
mandatory.

Since some versions I could create an OS X 64-Bit Mode standalone, but still
in 8.1.1 it says it is experimental.

What does it mean exactly? Is it experimental, because the last 1% of
functions are not fully tested and I could use it safely, if I would have
tested it with  my current program, or are there any general pitfalls, for
that I shouldn't use it?

 

Any experiences? Any recommendations?

 

Thanks

Tiemo
