Agreed, patch-loaded and patch-ready are different things.

In some of my patches, I take a systematic approach to startup
instead of having loadbangs dotted here and there. A subpatch
called [pd init] is often there, containing a single loadbang
and a big [ t b b b b b ... ], connected from right to left
order to a set of [s startx], [start y] ... objects.
The last thing on that list would be "ready". I'v found that
useful to precisely sequence the startup of patches with
initially unstable filters etc.


This doesn't help the cases of existing patches though,
unless we want to retrofit them all.
 
And it doen't help with Iohannes case where a [delay]
is placed after the [loadbang].
