So to what end are you redirecting these writes? Certainly not to save money, or to prolong the life of the SSD noticeably. You do realize that HDD platters wear out too? And don't have wear leveling as such and so by default write to the same first available sectors every time? Sectors that can also only be written to a set amount of times before becoming unreliable? The HDD with all it's moving parts will probably break long before the SSD does. In fact, any measurable effect will be hurtful to performance.
You'll be doing it just because you can then, and not because it will have any meaningful beneficial effect. I rather use the drive and gain the benefit of it's speediness. Just like a spinner! I write them off in a few years, and after that I retire them to light duty in other machines. Personally, I accept the minute extra wear, and consider the SSD as 'disposable'. Endurance on modern drives is into the petabytes or not exabytes. The controller might even fail before the NAND does.
Other factors, like capacity becoming unusable, or OS support and hardware changes, wil probably render this model of drive obsolete long before that. The difference is likely between wearing it out in 30 years versus in 28 years. But that negates the whole point of having an SSD. Think of it this way: you could 'protect' your SSD by preventing most writes to it. No, that won't impact SSD lifespan in any significant way. The last 5 years at least I haven't bothered. This was in the days that it actually mattered under heavy use (2006 - 2010 ish). I have done similar folder redirecting in the past on SSDs.
