To this, my mother would say: "Why keep it simple when we can make it
complicated?".

That's a valid computation if the extension was limited to use only
2-surrogate encodings for supplementary planes.
If we could use 3-surrogate encodings, you'd need
3*2ˆn surrogates
to encode
2^(3*n)
new codepoints.
With n=10 (like today), this requires a total of 3072 surrogates, and you
encode 2^30 new codepoints. This is still possible today, even if the BMP
is almost full and won't allow a new range of 1024 surrogates: you can
still use 2 existing surrogates to encode 2048 "hyper-surrogates" in the
special plane 16 (or for private use in the private planes 14 and 15),
which will combine with the existing low surrogates in the BMP.
