Thanks for your interest in the projects. Most changes from a 30 seconds review look reasonable.
However we don't apply changes this way. From your comments it seems we'd require about
five patches since the changes are of very different types.

Any pointers on this? (so I can learn)

Can't we just drop the parameter completely and wipe every trace of it?

Been thinking about doing this myself but always found something more interesting to do. Good.

Not sure if this buys us anything. I wouldn't react if original code was either way, but
changing it seems unnecessary.
