Following is the entirety of what Dan wrote:
"Then, to proceed, remove /dev/sda1 partition followed by grub-install?"
Nothing in that post makes it unambiguous that an MBR (MSDOS) partitioned disk
was not the subject of discussion.

The post Dan's quote came from, standing alone, as a whole, was confusion.
Absent clear indication of GPT context, the term "BIOS boot partition" is
ambiguous. It could easily enough be construed as the 16 bytes at LBA 0 address
01BEh, which in BIOS/MSDOS partitioning context is sda1.
Regardless, no partition needed to be removed, regardless of type, whether legal
or not, and better safe than sorry, which was why I wrote what I wrote.

I can't speak to how common it may or may not be, but I've used at least one
partitioning tool that expressly features an ability to rearrange partition
entries in an MBR table in either logical or arbitrary order. That definitely
can produce renaming/renumbering as a result, hence what I wrote: "depending on
the details..."
