I have to disagree with you, the ability for threat actors and LE to selectively backdoor code on server is important in any TM. Practicality is dynamic, TAs use the easiest method within the parameters of their objectives. It is reasonable to assume this attack would be the easiest given lack of other options. By your logic,56 bit DES is fine because most people won't see attackers that spend >$20k to crack their keys. Just like they won't see robbers who spend that much to break into their homes. Infosec is different than IRL because TAs can attack arbitrary targets easily with little personal risk. Also, hard attacks today can become common attacks a year from now and security for even the 99th percentile of users who get targeted attacks is important.
