The wiki suggests both tags together on a single way is

<div>what do you do when the coastline is split in several parts
(there may be various reasons for this, some have to do with
admin boundaries in cases where the island is split into
several administrative divisions that end at the coastline)?</div>

<br>
Make the place=island into a multipoygon relation. It has been done
and looks to work, as I recall where one island had boundaries for
national parks imposed on the coastline, ion another where beachg
asnd and scrub were imposed on the coastline. <br>

Look at the history as to when the gns tags were applied, if not
clear at the time of application then ask that mapper?<br>

<div>Overlaying ways is one of the possibilities (personally I
do not prefer it, but it is generally accepted, especially as
the only alternative in many cases are relations, which also
are contested), and you didn't provide any reasons why it
should be thoroughly rejected.<br>

<br>
I asked for ideas. I personally have thoroughly rejected overlaying
ways. What others do is up to them. <br>
<br>
There is an area that I know of where overlaid ways exist .. and it
is a real mess to edit as some nodes only join to one of the ways...
It was remotely mapped by an 'expert'. They objected to my
deletions, which are based on existing data and a little knowledge
rather than satellite imagery and guess work. <br>
