Yes, exactly, one issue that I've seen, at least in the Java world, is the original web application they have is so out of date and obsolete (but its still making money) that you literally have to bend over backwards to not mess things up which means severe restrictions on using new libraries, etc and then this leads to having to do stupid things like forcing people to write their own CSV parser because its too much hassle to put in a library for it and make sure it doesn't break anything.
