|No such thing as a small change|
Be a bit cautious when putting large amounts of data into settings such as free nodelet, signature, node template, etc. All settings get encoded into text and stored in a node which will (at least as things are currently implemented) silently be truncated if the result is longer than 64kB, perhaps losing all of your settings.
I've updated Free Nodelet Settings to report how much space is being used, including a note as to why that is important.
You should disclaim that doing as you "urge" also means that anybody who does so is subject not just to bugs but also to potential maliciousness. For example, it isn't particularly hard to set up a web server such that keypress.js will rarely serve up a hacked version that forwards the person's PerlMonks cookie to you in a private message.
Several potential ways to address such risks come to mind, with varying trade-offs. But I don't have time at the moment to go into those, so I just wanted to make sure people were aware of the risk, however small (given shmem's long history).
