Nope; bootloader flash chips use NOR instead of NAND flash precisely to prevent this. NOR flash guaranteed for a minimum of 100,000 complete rewrites of every cell, with no flash translation layer gimmickery. The downside is that it is very expensive, which is why a few dozen megabytes of NOR flash costs as much as many gigabytes of MLC NAND. Typical NOR flash chip; "Minimum 100,000 Program/Erase Cycles": https://www.gigadevice.com/flash-memory/gd25b127d/ NAND flash vendors often advertise "up to" a similar number of P/E cycles on their SLC devices, but you'll have a hard time getting them to guarantee that. And for TLC and MLC NAND you find in non-industrial products the number is more like 3% of that: https://www.kingston.com/en/blog/pc-performance/difference-between-slc-mlc-tlc-3d-nand TL;DR: bootloader flash chips are chosen such that they are nearly impossible to "wear out".
