Good question, Jean-François.
I seem to recall that typographers may make a distinction between
"black-letter" and "fraktur" forms, but even if they, the differences
are typographical, not essential. For the purpose of *character*
encoding, one would need to make a very strong rationale for disunifying
these.
This rationale is absent in document WG2 N3907 that requests these
characters.
Therefore, it seems these two additions should not have been made.

Version 7 of Unicode includes the following two letters:

There already were the following two:
𝔢 1D522 MATHEMATICAL FRAKTUR SMALL E
𝔬 1D52C MATHEMATICAL FRAKTUR SMALL O
For these, there’s an annotation:
@ Fraktur symbols
@+ This style is sometimes known as black-letter.
What’s the difference between U+AB32 and U+1D522?
Between U+AB3D and 1D52C?
