Ok, most likey some package maintainer hasn't update their boundaries
to work with 8.2.2.
Go with
cabal new-build --allow-newer
and maybe politely nudge maintainers to relax their dep.bounds
appropriately

@Michael Snoyman:
I returned back all .cabal-files and added compiler: ghc-8.2.2, `stack build`
printed out this:
---cut---
Error: While constructing the build plan, the following exceptions were
encountered:
In the dependencies for Cabal-1.24.2.0:
process-1.6.1.0 from stack configuration does not match >=1.1.0.1 && <1.5
(latest matching version is 1.4.3.0)
needed due to my-common-utils-0.2.0.0 -> Cabal-1.24.2.0
In the dependencies for versions-3.1.1:
base-4.10.1.0 from stack configuration does not match >=4.8 && <4.10
(latest matching version is 4.9.1.0)
needed due to my-common-utils-0.2.0.0 -> versions-3.1.1
Some potential ways to resolve this:
* Recommended action: try adding the following to your extra-deps in
/home/pavel/prj/automation/revcompl-mon/stack.yaml:
- base-4.9.1.0
- process-1.4.3.0
* Set 'allow-newer: true' to ignore all version constraints and build
anyway.
* You may also want to try using the 'stack solver' command.
Plan construction failed.
---cut---
After adding "allow-newer: true" build process starts, all looked fine until:
.../SimpleTagging.hs:281:51: error:
• Couldn't match type ‘Type’ with ‘DerivClause’
Expected type: [DerivClause]
Actual type: [Type]
• In the sixth argument of ‘DataD’, namely ‘derivs'’
In the expression: DataD [] ty' tyVars Nothing newCs derivs'
In the first argument of ‘(++)’, namely
‘[DataD [] ty' tyVars Nothing newCs derivs']’
|
281 | return $ [DataD [] ty' tyVars Nothing newCs derivs'] ++ showInst
| ^^^^^^^
which IMHO means that TemplateHaskell ("API") was changed from 8.0.2 to
8.2.2 because the same code is compiling with old GHC 8.0.2.

@Francesco: seems that code which I tried to test with new compiler is
out-of-date for it's Template Haskell "API".
@David: I planned to check existing code with new compiler (to be sure
that my code is OK), but seems that it needs to re-wrire the code, so
I will comment problematic test, GHC bug happens only is the test and
not in usual application code.
@all: Thanks a lot for all tips and help!!
PS. IMHO seems that Template Haskell gives more problems then solves
them :)

That's right, the template-haskell API frequently changes between major
releases of GHC.
