AFCI

No. They are not designed to require replacement.
GFCI have been working for more than 50 years. As others have pointed out the GF issues have almost all been caused by changes in the loads. Why don't the appliance manufacturers need to change their products to work with our infrastructure?
They keep adding more places that require GFCI protection, some involving things that never had to meet such strict leakage standards in the past making them not compatible with GFCI's.
 
The manufacturers have essentially bought the code making panels. They spend a lot of $$ with papers, demonstrations, etc. that are tailored to show things that favor using their product. You can bet they never show or talk about any product shortcomings, downsides, etc. even if they are aware of them when making any kind of presentation for the CMP's to see.
They didn't just buy the code making panels. The Code seminar I just took a week ago had a Square D, Siemens and Eaton reps for speakers. All three of those reps are on code making panels
