Patched fonts do not honor RFN license clause

[Finii]

Some fonts have a Reserved Font Name clause in their SIL license.
That requires you to change the name if you touch the font file.

For example:

# iA Writer Typeface

Copyright © 2018 Information Architects Inc. with Reserved Font Name "iA Writer"

# Based on IBM Plex Typeface

Copyright © 2017 IBM Corp. with Reserved Font Name "Plex"

# License

This Font Software is licensed under the SIL Open Font License, Version 1.1.
This license is copied below, and is also available with a FAQ at:

Adding something to the name (ie Plex becomes Plex Superior or iA Writer becomes iA Writer IF) is not changing the name.

Relevant snippets from the SIL license:

"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.

3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.

5.8 Is there any situation in which I can use Reserved Font Names for a Modified Version?
The Copyright Holder(s) can give certain trusted parties the right to use any
of the Reserved Font Names through separate written agreements. For
example, even if “Foobar” is a RFN, you could write up an agreement to give
company “XYZ” the right to distribute a modified version with a name that
includes “Foobar”. This allows for freedom without confusion. The existence of
such an agreement should be made as clear as possible to downstream users
and designers in the distribution package and the relevant documentation.
They need to know if they are a party to the agreement or not and what they
are practically allowed to do or not even if all the details of the agreement are
not public.
