Experience with combining tax updates in a single change package

Looking to get input from others on their experience combining multiple change packages into one. Normally we test and install each unique tax update with a single change package but might need to implement 24-C and 24-D as one.

There are support documents that show how this can be achieved but I also recall a document (that of course I cannot currently locate) that said combined tax updates were not supported/recommended.

So my questions for the community are:

1. Does anybody else combine multiple tax updates and if so what is your experience (success, no success)?
2. Any specific recommendations for going with this approach versus installing each one as they come out.
