No. This list, along with all the other data files, is now frozen

The following suggestions are being salted away as possible
updates for Unicode 4.1 (or whatever the next opportunity turns
out to be).

uses an italic-L, *not* a script-L, for the Lagrangian. (In more
than one instance, so this is not just a point mistake.)
The same site uses a script-L for the Laplace transform. So it
would seem to me that the Unicode annotation in this case is
> U+212F may as well have a second alternative 'natural exponent'.
Regarding the following issue for squared Latin abbreviations,
if you have specific suggestions for annotations, then make
them. However, as you surmise, I don't think the UTC is
likely to consider further annotation of this particular
batch of compatibility characters to be of much great
> Finally, a bunch of 'Squared Latin Abbreviations' (U+3380 -

>  U+3380 is named 'SQUARE PA AMPS' whereas other characters
