No not totally.

The seda component is on the roadmap for being improved for Camel 3.0

There is a few spots where it could be improved less invasive, and
then some areas where it may be a bit trickier.
However currently I would assume the InOnly could be improved to use
the async routine engine.

The trickier part is the InOut with the timeout. For timeout we would
need to either drop it completely.
Or introduce a timeout handler to keep track of timeouts, and what
follows. That is a bit trickier to do right.

This is related to the Async Bridge EIP from the SMX 3.x JBI world

And as this pattern is good. It could be worthwhile to check up on
what it would take to support the async routine engine to the fullest,
and as well how to handle the timeout / correlation of replies etc.
Hence why its scheduled for Camel 3.0.
