[Avodah] is mayim acharonim a chumra?

Summary (so far :-)

AISI:
Reb Shlomoh Pick has made a convincing argument that mayim acharonim is
still a chov.
And that Tosafos is essentially being lomeid zechus for those who do not,
but is not issuing a heter.


Unresolved chakira (as she'iltos would say bram tz'rich):
Is wiping one's hands on a napkin a valid alternative for mayim acharonim
or not?

Those who are not makpid on dibbur for mayim rishonim - should be makpid
on no dibbur before mayim acharonim
AFAIK this is a Sephardic understanding of teikef lintilah brachah.  (Caveat maybe some Sephardim learn otherwise.)

Those following the Rosh - who holds "teikef" applies to mayyim rishonim
- need NOT be makpid on no talking before acharonim - as verified by
ba'er hetev.
Neverthless, a form of hefsek seems to apply anyway as per Rambam,
machaber, and others and certainly eating after mayim acharonim is a
hefsek and I would add shinuy maqom etc.
But this din of hefsek is not really the hefsek of dibbur - although
probably the less hefsek the better because many/most posqim are machmir.

Arizal is makpid on hefsek dibbur by acharonim. Why? It is most likely
that he holds the Sephardic sheeta above that this is how he learns
Teikef. It is also possible that Arizal is makpid on dibbur by acharonim
al pi sod and NOT al pi halachah perhaps as an issue of better kavvanah.

Being makpid on dibbur in both cases of rishonim and acharonim is applying
"Teikef" both ways lechumra. IMHO since this is a derabbanan at most it
is an unnecesary humra.
Ksil bachoshech yahaloch is when one is tofeis the humros of 2 different
schools of thought.

Tangentially Today's Yoreh Deiah lesson dealt with this legabei zli,
mefapei'a, and kdei netilah. See sefer hasheetos, YD 105:4-5

PS
Baer Hetev 179:1 led me to SA 183:6 and MB 183:21
(I don't have MGA handy)
Where SA & MB seem to be makpid 
"Mishenasnu lo cos levareich lo yasi'ah hamevareich.."

Now if mayyim acharonim had triggered the no talking rule what's the
hiddush here? Why davka the mevoreich is assur to talk after taking
the cos?

Halo everyone who washed Mayyim Acharonim is assur to talk? This diyyuq
is apparently the ba'er Hetev's source that talking is OK.
