maxsend max should be the default
Not every server host is necessarily going to know about the maxsend
command, and those who do might not think to change it. Generally, if someone adds some files and starts hosting, and turns on "allow download", the intention is to allow downloading of all the files they added. There's no indication that, by default, it only applies to ones below a certain size, nor is there any indication for the host if people are being blocked from joining. Therefore, I think maxsend max
should be the default.
