During design phase it is the easiest to affect end result by setting specific goals to end product. For example aiming for thin product instead of relatively thin and easily repairable. The actual differences are usually relatively insignificant.

=== Useful life ===

At least some products have repeating redesign rounds when they are being in active production. Some component availability might change and replacements are needed. Or management deems incoming warranty cases too infrequent and they see opportunity to cut BOM costs.

When manufacturer has known good baseline that does not get too much warranty cases, they can start redesigning internal components while everything looks the same for consumers.
