It's not just that the raw encoding that becomes easier to relax with higher system resources - it can also be generically compressed using those same resources. I run my Windows machines with disk compression enabled, and that tames most "bloated" files and lets me fit a lot more into a 256Gb SSD. However, there is some appeal in defining the format to a fixed low fidelity, too, since it shapes the authoring process around conveying the content through the limitations - "the medium is the message." But they're more likely to be the source format than thr transmission format, in the same way that old video games designed for 8kB of working memory now end up with terabytes of video footage streamed to online audiences.
