These people always think their usage must somehow be what the base model is supposed to be. There are BTO options for a reason.
Well, sure if you want 8TB of SSD and 128GB RAM which is expensive overkill for many users. The debate is what is a reasonable starting point for the base spec of each machine, and at what point making it smaller would be "false economy". It's 2022 and 1TB of fast SSD shouldn't be an expensive indulgence.
The fuss over the M2 13" MBP is a good example of false economy: for whatever reason, Apple somehow can't use 2x128GB chips & populate both controller channels - the sensible response would be to drop the 256GB option and go to 512GB with 2x256GB, but instead they've used a single 256GB chip and effectively halved the bandwidth - even compared to the previous model 256GB 13" MBP. They've actually made the base MBP "defective by design" purely to preserve the "2019 called" base spec.
Sure, the base price is what it is because Apple factor in the extra cash they make from selling BTO options - that's the game every PC maker plays - but I think Apple crosses the line when they start
downgrading aspects of performance vs. older models just to preserve their pricing structure. Also, although it's hard to do 1:1 comparisons with PCs, most PC laptops at the ~ $1200+ now come with 512GB of SSD (even when it's comparable PCIe x4).
Even with the Studio, "good design" would probably be to fill all 4 slots with the smallest
economical sized modules (especially if you're not going to let users use the free slots for upgrades) to get the best performance.
Fortunately Apple have drawn the line with RAM and not made 8GB M1 Pros or 16GB Max's - but they're doing the equivalent of SSDs.
Also bear in mind that not everybody (esp. outside US/UK) is able to order BTO direct from the Apple store, you're less likely to find BTO models in stock at other suppliers and
certainly unlikely to see the discounts you might get on base models. Also, when shortages bite, it's the BTO models that get hit with long delivery delays.
