I found it is either that, an excuse to be really passive, or it's just an excuse for the character to be a cock-sleeve, excuse my language, for the other character. There's no substance.
Perhaps worth noting that I have had good experiences with people that wrote sub characters (or, rather, I have had one) but that was an expert writer. Shy, depressed characters are the same. It needs to be done well, or not at all.
Wait, for real!? Assen represent! And also Amerfoort, but that's where my apartment is, doesn't quite feel as homey as Assen :')
Cocksleeve made me giggle. But it's quite often very true.
And same, a friend of mine can write the shy, easily intimidated sort in an amazing way (one of her characters actually gets into a lot of odd situations, simply because he's very bad at saying no and walking away).
