Filetype is the same as CC 2018
InDesign CC 2019 (184.108.40.206) for Mac
Filetype is the same as CC 2018. Each version has been given a unique Filetype. The only exception is v6.0.0–6.0.3 (CS4), but it was fixed as a bug in 6.0.4. I also expect it to be fixed as a bug of 14.0.0 as well.
This has been done to preclude any new entries for CFBundleTypeOSTypes. The previous release, CC2018 had CFBundleTypeOSType as IDdD but for the new release, we have not created the new OSType entry as IDdE rather kept the previos entry intact.
Apple had deprecated any entries of the form of CFBundleType from 10.5 and now recommends using a UTType(Uniform Type Identifier) entry instead of creating CFBundleType entries. We might choose creating UTTypes in the future. However, for now we have stopped creating separate CFBundleTypes for the new releases.
It would helpful to know from you as to how you use these entries in your workflows so that we can suggest you an alternative.

I understand that migration to UTI is inevitable.
First of all, we hope to be able to get the created version of the indd file accurately and quickly. This is a long-standing desire.
Bridge.app displays the application information (XMP:CreatorTool) in indd, but this version may be inaccurate. We can not trust this information.
To know the real creation version in indd, we have to open that file, hold down the modifier key and select the About menu and watch the history. While dealing with large numbers of indd files, it is impractical to do this operation.
Filetype (CFBundleType OSType) was an attribute that can get version information accurately and quickly without opening a file. If this is gone, only the binary at the top of the file will remain. But this is more difficult for the user than Filetype.
We lose the means to get the creation version of the indd file accurately and quickly. We hope this problem will be solved.
Filetype is CFBundleDocumentTypes in Info.plist. In particular, the 4-character CFBundleTypeOSTypes is the same IDdD for both CC 2018 and 2019 InDesign documents.
This attribute was unique to each version. Using this wonderful attribute I make my own desktop application and use it. This app displays file icons by version, and also displays Kind of Finder information by version. I am disappointed because CC 2019 can not do this. There may be people besides me who use this wonderful attribute.
All available versions are installed.
The indd file made with the old version will be revised in later years. These must be opened in the same version. The indd file made from various versions come from the outside. These must be opened with the same version at this time. In order to deal with these, all available versions are installed.
