What motivated doing so? What exactly was/were your goal(s) in doing so?

It's not something I've ever done, but as I understand them, using either to
delete and recreate an existing partition should do that job, but compatibly
only if you know how to recreate the same size and have it start on the same
sector as it now does.

Any binary disk editor can move the slot 4 partition record to slot 3. That's
the only difference between your existing native partition being named sda4
and being named sda3. Do you understand the ramifications of making such a
change? As long as your existing Debian partition is referred to by name,
UUID or ID in bootloader config and fstab, it shouldn't matter the device
name resulting from its partition table entry.

Why the "need".

As the size recovered by your deletion of sda3 was minimal
(82116608-81920000=196608), you're probably best off, in terms of
complication, by creating another partition in its space. Once created, make
a new filesystem, and maybe mount it as /usr/local, /var/cache, /tmp or even
/boot (assuming you know and can deal with the bootloader complications
involved in doing so).
