No, I don't think so. 0.99 didn't have wrapper streams, limits (eg. read
only up to X bytes) were set to input stream directly, which made
wrapper streams very complex to implement.

Wrapper streams make things pretty neat. It's possible to implement for
example gzip or bzip2 wrapper streams for mboxes quite easily as a
plugin.
