This file is shipped as is without any modifications made to it — as if you had downloaded and installed it from the DITA Open Toolkit Project at SourceForge. So why this file warns against modification is unknown to me (and doesn't make any sense as far as I'm concerned).
I don't see there being any issues with making changes to this file as it is essentially a configuration type file (a list of variables that should be modifiable without breaking anything else, provided you don't muck up the standard structure). Without making changes directly to this file it would be fairly complicated to create a new file and redirect the DITA OT to use it instead.
