Boundaries in South Aegean

Following up on my post yesterday (https://forum.openstreetmap.org/viewtopic.php?id=71201), I checked in detail the boundaries for the South Aegean and found more discrepancies. I'm certainly offering to fix these issues myself, however, I do not feel entitled to change boundaries in Greece without contacting the Greek OSM community first and receiving their approval that the cases brought forward are valid and correct. Please check them and give me feedback so that we can improve the boundaries:

Case 17: Oxia

The island of Oxia is, according to geodata.gov.gr and GADM, part of the municipality of Symi (admin_level 7). It is not assigned to any municipality in OSM.

Case 18: Agios Emilianos

The island of Agios Emilianos is part of the municipality of Symi (admin_level 7) as reported by geodata.gov.gr. It is not assigned to it in OSM.

Case 19: Prasonisi

The island Prasonisi is not assigned to any municipality (admin_level 7). It is not included in any municipality according to geodata.gov.gr but that may be a mistake.

Case 20: Anydros

According to geodata.gov.gr, the island of Anydros is part of the municipality of Ios (admin_level 7). In OSM, however, it is part of Santorini (municipality of Thira). The English wikipedia page https://en.wikipedia.org/wiki/Anydros also suggests that the island belongs to Thira.

Case 21: missing islands (rocks) around Kos

According to geodata.gov.gr, there are a couple of islands (or rocks) that belong to the municipality of Kos (admin_level 7). The islands show up on Bing and Google satellite imagery but are not included in OSM.

Case 22: Megalo Glaronisi and Mikro Glaronisi

Case 23: East Imio and West Imio

These islands seem to be a problematic case. In geodata.gov.gr, both islands are part of the municipality of Kalymnos. In OSM, they are not assigned to any municipality (admin_level 7). East Imio is according to the current Greece-Turkey boundary in OSM located in Turkey, however the boundary is marked as disputed. East Imio is part of several conflicting relations: the state boundary is Mugla (Turkey), the administrative boundary is Aegean Region (Greece), and the country boundary is Turkey.
