We wanted to change niceness to accomodate the fact that some of the preparation tasks are low priority. For example, when a node sees that there is a new para was onboarded the node may start preparing right away. Since all other activities are more important, such as network I/O or validation of the backed candidates and preparation of the immediatelly needed PVFs. However, it turned out that this approach does not work: generally non-root processes can only decrease niceness and they cannot increase it to the previous value, as was assumed by the code. Apart from that, https://github.com/paritytech/polkadot/pull/4123 assumes all PVFs are prepared in the same way. Specifically, that if a PVF preparation failed before, then PVF pre-checking will also report that it was failed, even though it could happen that preparation failed due to being low-priority. In order to avoid such cases, we decided to simplify the whole preparation model. Preparation under low priority does not work well with that.
