I don't know if these two types of aggregation would be treated the same in RDA or not -- but it doesn't seem to me that previous cataloging rules really handled multiple works in a single published item very well. For example, there isn't a way to have two uniform titles (right?).

Depends on what context you're referring to. If you mean, say, a pair of 100 + 240 in a single record, then no. But for a compilation of two works by different creators with a collective title (aka aggregate manifestation title):

Under AACR2:
100 1- Name01
240 10 Uniform title01
245 10 Collective title / Name01 and Name02.
700 12 Name02. Uniform title02.

Under RDA:
245 00 Collective title / Name01 and Name02.
700 12 Name01. Uniform title01.
700 12 Name02. Uniform title02.

If no collective title:

Under AACR2:
100 1- Name01
240 10 Uniform title01
245 10 Title01 / Name01. Title02 / Name02. [assuming Title01 doesn't match Uniform title01]
700 12 Name02. Uniform title02.

Under RDA:
245 00 Title01 / Name01. Title02 / Name02.
700 12 Name01. Uniform title01.
700 12 Name02. Uniform title02.
