This comes up frequently. In many cases it seems the obvious solution.

Often, problems become apparent on further consideration: who will
read this vector of pointclouds? What operations must be performed on
it?

Frequently, these problems are better solved by republishing some or
all of the original points as a single PointCloud2 with a
categorization field. The data can be sorted on that field for
efficient access, sometimes that occurs naturally as a result of your
algorithm, anyway.
