In my former job (major brake designer/supplier) they promoted thechanging fluid and hoses yearly more as some have said as a legal protection but truthfully The fluid and hoses are designed with a 100k change interval goal.
A lot of places in the world do the yearly fluid changes as a matter of culture and quitefranklyit;s not a bad thing. Hoses,, it seems that modern brake hoses have a propensity for the rubber separating internally and creating internal check valves that cause brakes to drag or lick up, but this is more predominate in the auto section, not so much bikes.
Rubber hoses are required to give you flex in areas that move but also to dampen any vibration out of the system. If you had a system that allowed a full metal brake line you would still need a section of hose for vibration dampening, particularly with the modern advent of abs, you’d regularly crack the hard lines without that “flex” in the system.
Myself, I just don't replace the hoses just because some lawyer said so, look for evidence of bulging or cracking particularly around where the ends are swaged on and if you feel the need you can get braided lines that are better than oe for less $$$.
