Whenever you touch a file, there's always a risk. But, I think writing IPTC to the masters is OK. The gang over on ApertureExpert also advise writing the IPTC to the masters. I think it's the one spot where Aperture's "never touch the master" paradigm doesn't hold firm.

What are the pifalls of writing metdata (IPTC) to the masters.
The only pitfall is, when you mess up a batch change command, what is fairly easy to do, and write the wrong changes to the masters at the same time for hundreds of photos. Then you will not be able to restore the original IPTC captions and headlines from the original files, but will have to do that manually.
For example, what sometimes can go wrong, is to forget to change the "append" flag to "replace". Then you will append the new caption to the old, and that may not be what you wanted to do. Or you may forget to edit a predefined metadata preset, and apply a setting from the last import, with wrong location and caption data.
Before you ever use "apply to master", better triple check all settings carefully
